So this chapter sees a time jump after Gabby and Matt's surprise wedding, hope you enjoy it.

5 years later

"Allison, stop bothering your father, he has to get to work." Gabby grabbed her four year old daughter mid body slam and settled her on her hip.

"You shouldn't lift her Gabs, she's old enough." Matt tried to pry her from her arms but she pulled her out of reach.

"We've talked about this Matt, I'm pregnant not disabled."

"I know but you're eight and a half months pregnant and I don't want you to go into pre-term labour while I'm on shift. I don't want to go through that again." He kissed her lips, his hand sitting on her swollen belly. "Isn't that right Owen?" As if the baby could hear him, he felt a sharp kick against his hand, Gabby barely flinching under it. "See, he agrees with me."

"That means that you have nothing to worry about." She finally let Allison down now that she was sure that the little girl was a bit more calm. "Time to say bye to daddy."

"Do you have to leave?" She looked up at Matt with pleading eyes, Matt taking her in his arms.

"I have to but I'll see you again tomorrow morning."

"Stay."

"You know I can't Allie but if you're nice enough, maybe mommy will bring you to the firehouse to see me later?" He looked at Gabby who simply smiled at him.

"Only if you're nice." Allie kissed Matt on the cheek and extended her arms so Gabby could pick her up again.

"I'll be nice." She promised, putting her head on Gabby's shoulder.

"Stay safe." Matt and Gabby shared another quick kiss.

"I will, I'll see you later." They shared one last kiss. "And I love you."

"I love you too." Matt gave Allie one last kiss before heading out the door and off to fifty one.

"Let's go eat sweetie." Gabby put her back down and padded back towards the kitchen. Owen was starting to be heavy and she had back pains every now and then but she was hopeful that he wouldn't make an appearance for another week and like Matt, hoped he wouldn't come while he was on shift.

She had barely been off from ambo and at thirty-two weeks, her water had broke and it was late at night and he had been on a call when the ambulance had taken her away to give birth at Med, the pain too much to allow her to drive there herself. She had left a message while she was being wheeled in, hoping that he would hear it in time. Antonio was already on the way with Laura and the kids as well as her parents and Matt's sister Christie and his niece Violet too. They had settled her in comfortably in a room while they monitored her, her family arriving shortly after.

"Have you seen Matt?" She asked Antonio as soon as he set through the door.

"Not yet, I'll try calling him again." He patted her leg, leaving her with Laura and the kids while he made the call. Matt came running in only a few minutes later.

"I'm sorry babe, we were stuck at the scene. How are you feeling?"

"The contractions are beginning to be closer together." He kissed her and squeezed her hand. "I was scared you wouldn't be there on time."

"When I saw your missed call, I panicked. Cruz put the sirens on 81 so we could get here faster."

"Is everyone there?"

"No, they left back for the house but they'll come back as soon as shift is over." the nurse came in to check on Gabby and announced that it was time. She was wheeled into a delivery room and two hours later, Allison Casey had made her way into the world, both parents over the moon in love with their first born.

Hours later, Gabby had managed to clear most of the house work and Allison was dressed and ready to go. As promised, she had been nice and it was now time to make a little visit to firehouse Fifty one. She was happy to see that all the trucks were in except for ambo so she held onto Allie's hand tightly because every time they walked through the large doors, she became all excited to see everyone, not caring about the dangers that were hiding in every corner.

"Uncle Kelly!" She exclaimed, pulling free from Gabby's hold and running into his waiting arms.

"Hey pipsqueak, what are you doing here?"

"Daddy said that if I was nice that mommy would bring me to see him."

"Is that right?" The little girl nodded her head and smiled. "Then let's go see what daddy is up to." He kissed Gabby on the cheek as she came to their level. "How's my nefew doing?"

"He's been kicking a lot on the way here."

"Future smoke eater right there." He chuckled.

"Let him come into this world before you start a war to know who between Squad and Truck is better, please."

"Fair enough but Allie knows right?" He tickled her on their way in.

"Truck." She annouced proudly as they walked into the common room.

"That's my girl." Matt stood from the head of the table where he was sitting with the newspaper.

"Traitor." Severide whispered to Allie as he set her down, the little girl running towards her father who scooped her up in his arms, the rest of the house drowning in laughter.

"How are my girls?" Matt kissed Gabby and then Allie's cheek.

"Owen is hurting mommy." She pointed to Gabby's belly.

"Is that true?" He gave her a worried look.

"He's kicking a storm, it's fine." She waved him off.

"Are you sure?"

"Yeah. He always get's that way when we come here."

"That's my boy." He rubbed her belly. "So looks like Allison was nice with mommy."

"She was very nice. I think she wanted to see her dad."

"Who wants some jell-o?" Allie perked up when she heard Otis call for her favourite treat.

"Me." she wiggled out of her dad's grasp and ran towards the kitchen where Otis was waiting for her.

"You got her Otis?"

"Sure thing lieutenant."

"Let's go sit in my office." He helped Gabby back up to a standing position. They walked at Gabby's slower pace and she sat on his cot, Matt closing the door behind them. "Are you sure that you're ok?"

"Yeah." She smiled at him but he watched as her hand flew to her lower back.

"Gabby?" He lowered himself to the ground, crouching so he could take a good look at her.

"Contraction." She huffed, riding it out.

"How many?"

"First one." Now her hand flew to her side. "Now he's kicking."

"Come on, I'll help you lie down." She didn't object so she let him help her to a horizontal position on the cot. She took a few deep breaths and she watched as Matt looked at his watch, no doubt trying to see how far apart her contractions were. She was able to take a few deep breaths before another contraction hit her, this time harder. "Talk to me Gabby."

"That one hurt."

"Do you want to go to the hospital?"

"No, they're not close enough." She breathed in and out deeply. Matt knew she was too stubborn to give in but he could see that she was in pain.

"Tell me what you need then." If he couldn't force her into going than he'd do anything to make her feel confortable.

"Just bring me a glass of water and a wet cloth, I feel like I'm sweating up a storm."

"I'll be right back." He kissed her forehead and he left to get what she asked for. He returned minutes later to find her sitting in his cot, a hand firmly planted on her back.

"Are they closer?" He sat next to her. He had told the rest of the house about Gabby's contractions and they hoped that the girls from Ambo would be back in time if they needed to rush her to the hospital.

"Yeah. I think he's just about ready to get here." She looked down at her legs, noticing some clear liquid trickling down.

"I think so too." He used the cold cloth to wipe her legs down and then he helped her to her feet and they slowly walked towards the common room where they all stood when they saw the couple walk towards them.

"It's time?" Shay asked, taking a step forward.

"I think so." Gabby breathed out.

"Alright, let's get her into ambo. Chief?" He looked at the man who was now standing directly in front of him.

"Herrmann can be acting lieutenant and Allison is in good hands. Shay, Brett, take care of her and keep us updated?"

"Will do chief." Gabby insisted that she walk all the way to the ambo even though Brett was arguing with her that she could just bring the gurney to her.

"You should know by now not to argue with her." Matt exchanged a smirk with Brett who tilted her head to the right.

"I think she'll need to remind me one more time." Matt and Shay finally helped her onto the gurney before the girls lifted her inside, Matt taking the seat next to her, holding her hand in his larger ones.

"Just keep breathing babe." He brought her hand to his lips and kissed her, Brett leaving the house towards Med. They drive was short and she was quickly wheeled into maternity and settled into her room to be monitored but things were moving quickly and in less than thirty minutes, she was already good to start pushing.

Matt held onto her hand as the doctor instructed her to push, letting her squeeze it as hard as she could, the pain he was feeling far less intense than the one he knew she was experiencing. He had hated seeing her be in so much pain when she had given birth to Allison and this time wasn't any different. With each contraction, she had to push and the pain that was written on her face said it all.

"Just one good last push Mrs Casey." And with the following contraction, Gabby gave one last, strong push and Owen's screams were filling the room. The nurses quickly took him away to clean him after Matt had cut the cord and he was then returned to her where she started brestfeeding immediately, the bond between mother and son starting right then.

Matt watched the woman that he called his wife and that he loved more than anything in this world cradle their son in her arms and he was overjoyed. He pushed a stubborn lock of hair away from Gabby's forehead and placed a kiss on it and then on their son's head.

"He's perfect." He whispered.

"He is."

"You did great." He soothingly ran his fingers through her hair.

"We did great." She looked up at him with a smile. "Do you have any news on the house?" She asked as Owen was now asleep against her chest.

"I just told them that Owen was here and Shay said they'd be there as soon as they could." They knew that Fifty one was one of the busier houses and that it was possible that they might not see them until morning but just then, Shay poked her head into the room.

"Knock knock." She smiled. "Are you guys up for visitors or do you want us to come back later?" Shay had Allison in her arms but you could see that she was impatient to meet her new baby brother.

"You guys can come in." Shay and Severide were the first to come in but soon enough, the whole house was packed inside the large room. The hospital had a strict visiting policy but they also knew that Fifty one was family and there was nothing that was going to stop them tonight from spending a little bit of time with the newest addition to that family.

Allison was the very first one to hold Owen, Matt instructing her into a large hospital chair, placing him in her arms. "Be careful ok." He knew that she would be but he also knew how excited she was so it was just a reminder.

After that, everyone took turns in holding Owen, the newborn completely smitten with everyone. He was being passed around, looking at everyone and he never complained once except when it was time for another feeding. Shay reluctantly gave him back to Gabby and chief Boden managed to pull the whole house out so the new family could get some quality time together.

A few days later, they were all set to bring him home. After they had all settled in, Matt had gone to run a few errands since they hadn't been home in a few days. He wanted to bring Allison with him to give Gabby and Owen the chance to rest together and get close but she wanted nothing to do with it, wanting to stay with her mother. "You need to be nice for mommy and Owen ok? Because mommy is very tired and your bother needs to rest too."

"Yes daddy."

"Ok, I love you guys." He kissed Allie on the cheek and left. The tv was on at minimum volume and the girls were watching some cartoons on television but Matt wasn't expecting the sight he had in front of him when he returned home. Gabby was staring at Owen who was asleep in her arms and Allie had her head on her lap, fast asleep. "Looks like the last few days tired you out." He smiled at Gabby who looked down at Allison fast asleep.

"Looks like it. Care to join us?"

"Absolutely." He put away what he had bought and took a seat next to Gabby, placing his arm around her shoulder. "I can't believe how lucky I am." He placed a kiss on the top of her head.

"I'd say. When we first met, our paths were only meant to cross once and we were supposed to go our seperate ways." She remembered that time like it was yesterday.

"Hallie had left me and Mills had left you and it was supposed to be nothing more than a one night stand." He added.

"And it turned out to be so much more." She looked down at her two sleeping children.

"Seven years and two beautiful kids later, I couldn't have asked for a better ending."

"It's perfect."

"To many more years like this."

"To the rest of our lives." They shared a tender kiss and they spent the first of many days as a happy family, both getting the happy ending they dreamed of.
