Seems like people love Dad Jay so adding more of that in here - but had to throw in some Will too :) Hope you like it!

Jay rubbed his forehead tiredly. It was approaching dinner time, and he was fairly confident his little girl had missed lunch. He'd managed to suck down half of the smoothie Kim procured for him, but the cup she'd brought for Piper was melting on the ground beside the plastic chair he was sitting in. It felt like a perfect metaphor for the last few hours – everything was fine, and then everything was melting down.

"Upton's on her way back," Ruzek informed him carefully, "Said they just ended."

Jay lifted his head and picked up his cell before dropping it back in his lap. "Phone's dead," he muttered, "Shit."

"I got it, man," his coworker insisted, holding out a phone charger, "It's going to be okay."

"Is it?" Jay managed, "Because our boss has a bullet in his shoulder and my kid saw it happen. Same kid who's already had a concussion and pneumonia this year." He rubbed his cheek tiredly. "Sorry."

"Don't worry," Ruzek replied, "Voight's too stubborn to die, and Piper and Erin are cut from the same cloth. Kid's going to be fine." He gestured to the entrance of the waiting room, "Upton's got her."

Jay stood when he saw his partner in the doorway, holding the hand of a very woozy version of his little girl. Hailey caught her when she stumbled slightly, hoisting the child into her arms. "You did such a good job," she whispered against Piper's head, "So good."

"Thank you," Piper replied meekly, "Sorry for getting dizzy."

"That's okay," she replied. "Jay's here now." She looked at her partner, concern written all over his face. "She's incredible," Hailey informed them, offering a small smile over Piper's head, "Did her best. She's a bit dizzy, and her memory's a bit fuzzy." She ran a hand over the top of Piper's hair, "I think the lights in the hospital are bugging her head."

Jay grimaced and held out his arms. "Hi little bug," he whispered, allowing his child to melt into his shoulder, "Your head's hurting, huh?"

"I don't want it to," Piper mumbled against his neck, "I'm trying to be fine."

"I know," he cooed, "You did a great job." He gave a grateful smile to his partner. "We're very proud of you."

"'s Hank okay?" she croaked, "Where's Erin?"

"Erin's with Hank now," Jay said gently, "He's going to be okay."

Piper let out a breath of relief. "I was so worried 'bout her," she whispered, "'cause I know what it's like to be worried about your dad." She held closer to Jay when he pressed his lips to the top of her head.

"I love you," he murmured, "So much." Jay exhaled and looked around at the rest of his team. "I don't know how long Erin's going to be, but she's probably going to want to spend the night with Hank." He looked down at his little girl, whose eyes were squinting from the hospital lighting. "I might try to take you home, Pipes."

"I'm okay here," she insisted, "Erin needs you."

"Erin's alright," Jay promised, "She's with Hank, and I've got you." He stroked the back of her head gently. "I know you didn't want to have Dr. Manning take a look at your head, but I think you might have a concussion."

"I don't want a concussion," she replied in a small voice, "I wanna go back to school."

Jay swallowed and exchanged a look with Hailey. The fact that Piper wanted to go to school was huge progress, but he could tell by the fragility of the little girl in his arms that she was nowhere near ready to go back – not after the eventful Sunday they were still experiencing.

"You're going back," Jay said, "Just not tomorrow." He paused and glanced into the waiting room, hoping to see either his brother or Dr. Manning.

"Let me see if I can find your brother," Hailey suggested, "Any word on Hank?"

"Going to be fine. He's stubborn," he replied, continuing to rub the back of Piper's head. He frowned when his fingers reached a raised lump. "Did you bang your head, kiddo?"

"I don't know," Piper replied dejectedly, "I'm just tired now."

Jay resisted the urge to sigh. Piper was slowly working on the melted smoothie, back in his lap after an incredibly long day. Erin was still in with Hank, and his brother had informed him that Piper probably had a low-grade concussion, but there wasn't much that they could do beyond keep her comfortable.

And he couldn't keep her comfortable.

The lights in the hospital, similar to her first concussion (the fact that he could count his child's concussions turned Jay's stomach), were bothering Piper. She was attempting to be agreeable, but he knew his kid, and he knew she wasn't feeling it.

He just wanted to take both of his girls home, but his other girl wanted to be in the hospital with her dad. And he couldn't be two places at once.

"I'd offer to bring her home, but I don't think you want to put her down," Hailey said gently, "How about some coffee?"

"Thank you," Jay exhaled, "That would be great."

"Erin doesn't want you drinking so much coffee," Piper piped up sleepily, "She says you need to sleep more."

Hailey shot a look to Jay. "You are so right, Snipes," she said fondly, "I'll grab Jay some tea, how about that? Would you like anything? Maybe some juice?"

"Sorry," Piper mumbled when Hailey turned away, "Erin said you gotta look out for yourself and that too much coffee isn't good, and I get to keep an eye on you when she's not looking."

He managed a small smile. Erin had subtle ways of looking out for him, and a lot of them involved their little bug. She knew he wouldn't balk at Piper's suggestion for him to skip the coffee, but if it came from Erin, he would be none too pleased. "Erin sends you to deliver the hard information, huh?"

"You do the same thing," Piper told him, pulling back slightly to meet his gaze, "You think I didn't realize that you ask me to wake her up when she's on the couch instead of you?"

Jay chuckled. "I guess you're right. Neither of us can get grumpy at you, because you are the sweetest kid on the planet." He instinctively held her closer. "Are you hungry at all?"

"Not really," she replied, resting her head back down on his shoulder. "I had fun with Hailey and Will, but I still really missed you guys."

"We missed you so much," he said thickly, "Me and Erin had a good time together, but we both decided we have the best time when we're with you." He kissed the top of her head gently.

Erin emerged from the double doors, relief all over her face. His girl was teary, but that wasn't unexpected given the fact that she was carrying twins and had just found out her father figure was in the hospital. "He's okay," she announced to the remaining people in the waiting room, "Will get discharged tomorrow morning, but he's already trying to break out early." She gave a smile, "Still the same Hank."

The team let out a collective sigh, and Erin closed the gap between herself and her family. "Hi, sweet girl," she cooed, running her hand over Piper's head, "How are you feeling?"

"Better," Piper said softly, "I had some smoothie."

Erin nodded and then looked up at Jay. Something was off about her little girl. "Concussion," he said grimly, "Slight, but we should keep an eye out. Big bump on the back of her head."

"Oh, Noodle." Erin stroked her sister's cheek, "I'm so sorry, baby." She frowned when a few tears leaked out of Piper's eyes, "Are you feeling sick?"

"No," she whispered tearfully when Jay kissed the top of her head, "I just remembered that nobody ever gave me nicknames before. And now I got so many from you guys." Piper gave a small smile, "And I missed you a whole lot."

Erin felt her heart melt. "We missed you so much," she replied, leaning up to kiss Piper's nose, "You're our first baby." She smiled when Piper's lips lifted further. "And we're so proud of you. Hank was telling me that you knew how to use his radio and that you called for help?"

Piper gave a small nod. "I saw Jay do it before," she said, "B-but I dropped my phone I think."

"That's okay. We'll find it, or get you a new one," Jay assured her, kissing Piper's head again. "All that matters is that you're safe."

Erin nodded. "I was going to spend the night with Hank," she said as lightly as possible, "But I know he wants to see you, Noodle. Would you be okay with that? He's all cleaned up and feeling much better."

"Is he hurting?" Piper asked softly, "Like when Jay got shot too?"

Jay resisted the urge to grimace. His little girl had been subject to so much violence in her short life and it broke his heart. "Not too bad," Erin said, "He was more worried about you more than he was worried about him." She tucked some loose hair behind Piper's ear and frowned slightly when it was slightly crusty from Hank's blood. "We should get you cleaned up too."

Piper gave a grateful nod and rested her head back against Jay's shoulder.

"Hey, Hank," Erin greeted after knocking on his hospital room door, "Brought you a little visitor." She smiled and gestured for Jay to enter, Piper still in his arms.

"There's the kid who saved my life," Hank rasped, "Hi, Peanut." He offered a smile, "I'm going to be alright, thanks to you."

Piper glanced at the machines and various wires attached to the normally stoic sergeant. "You're okay?"

He nodded. "I am. Getting out of here tomorrow morning, and then a few weeks of rehab and I'll be good as new." Hank narrowed his gaze slightly. "Were you hurt, kiddo?"

"I'm okay," Piper said bravely, "I was more worried about you, 'cause you were bleeding so much." She swallowed, "I tried to go with you, I think, but the man in the ambulance said I couldn't."

"You called them and got me help," he reassured her, "I can't thank you enough, Peanut. And I'm sorry we didn't get a chance to do all the cooking we planned."

"We can do it another time," Piper said softly, "When Jay and Erin go on dates."

Erin chuckled and stroked Piper's hair gently. "You're always thinking of others, aren't you, Noodle?" She kissed the child's head. "I was going to have Jay take Noodle home to get her out of the florescent lights, and I'll post up right there." Erin gestured to the couch, "And before you say anything, you're not telling me no. These two beans will understand that their mommy needed to spend a night keeping an eye on their grandpa."

She paused, realizing that while she wanted to be there for Hank, there was another little person who considered her to be her mother that needed her too. "Is that okay with you, sweetheart? You're going to head home soon with Jay to get some good sleep. I'm just going to spend the night here with Hank, make sure he stays-"

"I'll be okay," Piper promised quickly, "You gotta be with your dad. And I'll be with mine."

Jay laid on the floor of Piper's bedroom, staring up at the ceiling. A big part of him just wanted to climb in bed to snuggle with his little bug, but he wanted her to be as comfortable as possible, and if Erin called him or he shifted during the night, he didn't want her to wake.

Piper managed to take a shower herself and immediately crawled into bed once she put on her pajamas. Jay had done his best to make her bedroom as dark as possible knowing that lighting could trigger headaches. Thankfully, his little girl settled rather quickly after a traumatic day, and Jay was grateful.

Erin texted that she was fine, that the babies were fine and that she was going to try to sleep some. Hank was sleeping and resting as comfortably as possible, and she was coming back in the morning and had the day off to take care of Piper.

He hadn't even realized that with his boss out of commission, there was still work to be done. He was needed even more at the district than before, and as much as he wanted to spend the day with his girls on the couch, his job needed him out on the streets.

It was honestly enough to make him want to quit and become a full time stay at home dad.

Sure, he loved his job. He loved that he got to protect the city he loved and keep the people he loved safe by getting bad guys off the streets, but it paled in comparison to how much he loved being Piper's dad. Getting to make her lunch in the morning, watching as she slowly ate the granola and fruit he'd set up for breakfast, making sure she had her homework and an extra layer in case she got cold during school – all of it filled him more than any other job ever had.

His thoughts were cut off when he heard a plaintive whimper escape from his little girl's lips. Immediately, Jay sat up, hoping to quell the nightmare before it escalated.

"Daddy, Daddy," Piper cried, thrashing against her sheets, "No, please, no."

Jay felt his heart swell and break simultaneously.

Only in his dreams did he ever really let himself think about Piper calling him Dad. He knew he was her dad, and she knew he was her dad, but he never wanted to put that expectation on her.

But hearing his little girl call for Daddy in her tortured sleep pulled at every heartstring he had.

Because there was a chance she wasn't dreaming about him.

He hastily got to his feet. "Hey, hey," Jay cooed, "Shh, Pipes. You're okay." He swallowed the lump in his throat and placed a gentle hand on her arm. "It's Jay, you're okay."

Piper startled and immediately scrambled back on the bed before meeting his blues with her petrified greens. "Just me," he managed, "Just me here. You're safe."

"I-I-I thought he got you," Piper gasped, tumbling into his arms and clinging tightly to his t shirt, "I dreamed he got you like he got Hank."

"I'm here," Jay promised, holding her close, "I'm here, baby. You're safe with me. We're both okay." He wrinkled his brow in confusion when Piper scrabbled at the collar of his t shirt with her shaking fingers, "I'm okay."

"You…you're not bleeding," Piper breathed, sagging against him heavily when it finally registered in her nightmare-addled brain that Jay was alive and in her bedroom, "I was so worried."

"Not bleeding," he confirmed, pressing his lips to the side of her head, "I'm alright." He placed a hand on her back, hoping to slow his child's racing heart.

"I-I never wanna lose you," she whispered, "I can't, I need my dad."

"And I need my kid," he replied thickly, "Not going anywhere, kiddo. I promise. I love you too much." He managed a sad smile when Piper snuggled closer to him. "You're mine forever."

Jay ran his hand over Piper's small head. "Does your head hurt?" he asked softly, "Do you feel sick?"

Piper sniffed. "Not so bad," she managed, tilting her head up slightly to meet his worried gaze. "C-can we go see Erin? And the babies?"

He wrinkled his brow. Erin's last text had been over an hour ago when she said that she was going to try to close her eyes for a few hours while Hank slept as well. She'd confirmed that she was fine on the couch in his hospital room and that the older man was doing well. Jay wasn't sure if Piper's idea of checking on Erin was a trip to the hospital, or if she thought her big sister was across the hall. Either way, he was going to have to tell her no, and it was one of his least favorite things to say to his little girl.

Piper was ordinarily an agreeable and sweet kid, who really didn't ever ask for much. Unlike the cautionary tales that the parenting books warned him about, Jay and Erin rarely had to tell Piper no, only because she never asked for anything out of the question.

"She's at the hospital right now," Jay said carefully, "With-"

"Are the babies okay?" Piper spluttered, "Is Erin hurt?"

"No, no," he said quickly, hoping to keep his child calm by continuing to gently rub her back. Piper had been slightly out of it earlier given the concussion, which according to Dr. Manning was to be expected, but Jay hated to be the bearer of the news that her sister wasn't in her bed, and was actually several miles across town. "She's with Hank, just making sure that he gets rest and is on his way to feeling better. Erin and the babies are just fine."

Jay grimaced when Piper let out a harsh gasp. "She's okay," he continued, "I was texting with her earlier, while you were sleeping. She's going to be home tomorrow after she makes sure Hank is all settled in his house."

Piper managed a tiny nod, tears welling in her eyes. Jay's heart cracked. He could tell his little bug was trying to be brave, but after a weekend apart, bearing witness to a shooting, with someone she knew and trusted no less, on top of a concussion, Piper's ability to remain stoic and mature was very limited. "We could call her," he suggested, "Would that help?"

She sniffed, tears spilling over her cheeks. "Erin's gotta sleep for the babies," she croaked, "We can't wake her up just 'cause I miss her." Piper's eyes widened slightly. "And I woke you up too, and you gotta sleep."

"Shh," he soothed, "Pipes, you can always, always wake us up if you need anything okay? Especially if it's because you're missing us." Jay wiped Piper's cheek gently. "If you're ever feeling sick, or sad, or you just want some snuggles, we want you to wake us up."

Piper buried her face in his neck. "I missed you so much," she whispered, "Me and Will had fun but he doesn't snuggle like you and Erin."

"Snuggles with you are my favorite," he murmured, kissing her head again. Giving kisses to his little girl never got old. "I missed you a whole lot. Me and Erin both."

"C-c-can you stay here?" She tightened her grip on his t shirt, "I wanna stay with you, please."

"I can," he confirmed, "Whatever you need."

"Snuggles with my dad," Piper replied sleepily, "That's what I need."

Jay's heart swelled. When he first met Piper, all he wanted to do was lift the forlorn and broken child into his arms, hold her tight and never let her go. She had been nervous and quick to startle, for good reason. It had taken weeks for a hug and months for her to accept snuggles and kisses from both him and Erin. He was constantly amazed at how far his little bug had come from when he first met her, but even from months ago. Earlier that year, he wouldn't have guessed that his little girl would so readily accept comfort from him or that she would verbalize wanting to snuggle with him. He was so proud of her.

He beamed. "Let's get you comfy," he determined, settling against the headboard, little girl still in his lap. Jay swallowed the lump in his throat when Piper settled against him and let out a content exhale. He couldn't love his little bug more.

Erin shifted on the couch in Hank's hospital room, doing her best to get comfortable. Hank was sleeping peacefully, and her last check on the baby monitor had Jay in Piper's bed, the little girl sleeping against her dad while he snoozed against the headboard. Her chest had ached – she missed her little bug so much, and she loved just how much Jay loved Piper.

"Hey," Will greeted softly, entering the hospital room bearing what appeared to be a large pillow and a plastic visitor's chair, "How's he doing?"

"Good," Erin confirmed, shifting again and offering a small smile, "Thanks for checking on him."

"I'm here to check on you, actually," he replied, "And my little nieces or nephews." He held out the pillow for Erin. "That couch can't feel good on your back, and you should be keeping your feet elevated to avoid swelling."

Erin could have cried. Her back was bothering her, especially after the long car ride. "You're a lifesaver," she said gratefully, sitting forward for Will to place the pillow behind her, "Don't know what we'd do without you."

Will grinned and adjusted the chair before carefully lifting his future sister-in-law's ankles. "How's this?"

"So much better," Erin said with an exhale, "Thanks Will."

"Of course," he replied, taking a tentative seat beside her. "You alright?"

She gave a small nod. "I haven't felt the babies kick," she whispered. Erin ran a hand over the left side of her bump, "And I'm getting worried."

Will wrinkled his brow. "You're sixteen weeks? It's a little early for you to be able to feel the babies moving." He tilted his head to the side. "I could take a quick look, if you want?"

"Please," Erin breathed, "I just…I can't stop thinking about the worst case scenario." She swallowed. "I was trying not to be so worried but then Jay and I went away for like two days and Hank gets shot and Piper gets concussed again and-"

"I get it," Will promised, "You guys have been dealing with a lot. Is it okay if I touch your stomach?"

Erin nodded and bit her lip. "Have you been having any pain?" he asked as he brought his hands to her belly, "Cramping, bleeding, that kind of stuff?"

She managed a tiny nod. "Cramping, I think. It's why I'm worried. I-I've been cramping for like weeks and it hasn't gotten better." Erin widened her eyes when Will pressed slightly, "Is something wrong?"

"No, no," he assured her, "You're building a home for two, Er. You were tiny to begin with, so your ligaments, and your uterus is stretching to accommodate two little humans. Pretty soon they're going to be encroaching on your lungs and stomach too, so you might have some tummy trouble or difficulty breathing. But all of that is normal." Will gave a smile. "Feels to me like you've got two very strong Halsteads in there. But if it will give you peace of mind, I could arrange an ultrasound."

Erin sniffed and rubbed her bump. "We have one in two days," she said, "I-If you think things are okay, we can wait. I just…" she swallowed, "I don't want to fuck up these kids like my mom did with me and Piper. And Teddy." She dragged a hand through her hair. "Jay bought this book about in utero trauma because he read an article about early intervention for kids coming out of foster care. I-I honestly probably shouldn't have read it but I did and now I just can't stop thinking about all the pain she must have gone through before she was even a week old. And Teddy too."

"You couldn't have stopped it then," Will reasoned, "But you're doing everything you can now to keep these two safe and healthy."

"I know," Erin choked out, "I'm just worried that me doing everything I can for these guys means that Piper's going to feel forgotten. I-I mean, when Teddy was born it was like I didn't exist. My mother never had time for me or anything and I never want Piper to feel like that. You…you were the oldest child. What was it like when Jay showed up?"

Will managed a small smile. "I'd never been more excited," he said honestly, "I don't remember a ton from the beginning because I was little but growing up, he was my best friend. We got into all kinds of trouble. And my mom, she never made me feel like either of us were a favorite or more important or anything." He ran his thumb over Erin's belly gently. "I mean, my dad did. I didn't realize it at the time, but I know it now. But my parents aren't you or Jay, Er. You guys are already so great with Munchkin. She knows how much you love her. And she's so excited for these two."

"Really?" Erin widened her eyes, "You're sure?"

"Oh yeah. Half the stuff we talked about this weekend was how to be the cool big sibling. She was worried that because you're the older sister, she wouldn't be as fun, since I'm obviously way more chill compared to my little brother, but I explained that you're her mom, so she gets to be the big sister to those little guys."

Erin wiped her eyes. "Thank you," she whispered, "For loving her. And for looking out for her. And me too."

Jay stood at the kitchen sink, Piper on his hip. He was carefully running a damp washcloth over the back of his child's neck after she woke up nauseated from the concussion and promptly was sick all over herself, her bed and him. After anxiously waiting outside the bathroom door for Piper to shower, he brought his little bug back into his arms. She was thankfully sleeping soundly on his shoulder while he wrestled with the bedding and laundry one-handed before he proceeded to the kitchen to hopefully get her something to eat.

His brother had sent a picture of Erin snoozing on his shoulder and informed him that he'd take both Erin and Hank to the sergeant's house to ensure he was set up properly before bringing Erin home to her family. Hank's prognosis was very good, and the man had been adamantly against any type of babysitter, but settled on the fact that Erin would drop by to check on him in the evening, and that various members of their team would be checking in as well.

"Jay?" Piper mumbled sleepily, "Jay?"

"I'm here," he assured her, placing the washcloth on the counter, "Are you going to be sick, Pipes?"

She shook her head slightly. "How come Erin isn't home yet?" she asked, "I miss her." Piper's voice cracked, "I want her."

"I know," he cooed, adjusting his little girl so she was resting against his chest, "I know, baby. Erin's on her way. She and Will are getting Hank all set up at his house, and then she's coming home." He grimaced when Piper whimpered. "You just can't catch a break, can you?"

She sniffed. "Sorry," she croaked, "For bein' a mess this morning."

"Oh, kiddo." Jay shook his head. His little girl had certainly picked up on some Erin-lingo. "You're not a mess. You hit your head." He tried to smile, "And it's a very pretty little head."

Piper's lips lifted slightly. "It doesn't hurt too bad," she offered, "I just got dizzy from the light." She lifted her head, "Sleeping helped. And I feeled safe in bed, 'cause you were with me."

Jay managed an actual smile. "I'm glad. Do you think I can set you down on the counter here, just to take a look at your head? I want to check your eyes too." When Piper gave a nod of assent, he placed her gently on the kitchen counter. His little girl's eyes were clearer than they had been the day before, and the swelling was down significantly on the back of her head. He let out a breath. She was on the mend. He stroked her cheek, heart aching when his child leaned into his touch. "I'm sorry you're hurting, Pipes," he whispered, "I wish there was something I could do to help."

"Just bein' with you helps," Piper said, rubbing her eyes tiredly. She tried to smile, but Jay could tell his kid was hurting.

"Oh, I think that's Erin," he said when a he heard a key in the lock on their side door, "She's home."

Piper looked over to the door as Erin entered, quickly closing the door behind her. "Hi. Will got a call and had to run, but he dropped me off." Erin dropped her bag and kicked off her shoes, "How's she doing?"

Jay leaned down to kiss the top of Piper's head. "Sick from the concussion this morning," he said, "But I think a bit better, right Pipes?"

She managed a tiny nod as Erin hurried toward her family. "Hi, Noodle bug," Erin cooed, smoothing Piper's hair back, "You got sick, huh?" She frowned when Piper gave another tiny nod. "I'm sorry, baby. I know it's been a tough few days and concussions are just the worst."

"They suck," Piper mumbled, rubbing her eyes, "I know I'm not supposed to use your words but that's all I can think of."

Jay managed a small chuckle when Erin blanched slightly. "You two girls have had too many concussions," he said, pressing his nose into Erin's hair, "But maybe a good lie down would help? I know Erin didn't sleep too much last night."

"Will ratted me out," Erin said, hoping to get a smile from Piper, "But he checked on the babies last night and said we were all doing well, which is good news. Just need more rest, which I think we can do together, what do you think?"

"The babies are okay?" Piper asked, "You weren't too stressed?"

Erin shook her head and put one hand on her tummy. "Babies are okay, but I'm focused on my first baby today." She leaned forward to kiss Piper's forehead. "How can I help, sweetheart?"

Piper snuggled into her shoulder. "Mom snuggles," she determined sleepily, "I got Jay all night but I didn't get you for the whole weekend."

Her heart leapt. "That can certainly be arranged," she said, smoothing more of Piper's hair back, "How about Jay helps you upstairs and then I can take a nap with all my babies, hm?"

She nodded. "Jay too," she said, holding her arms out for her dad to lift her up, "Snuggles with both of you is the best."

Let me know what you think!
