Erin had come up with a grand plan for how she was going to tell him. Well, as grand as a 'we're pregnant' announcement could be. She had known for three days now, but she wanted a special way to tell her husband that they were expecting their first child. She knew how much he wanted kids; simply handing him a stick that she'd peed on wouldn't suffice. Her doctor's appointment was in a couple of days, so there wasn't much time to stall—she had to tell him.

She found herself in the drugstore across the street from their place after she missed her period. Her periods were always on time; no matter the stress of work or the fluctuations of her sleeping schedule and diet, it stayed consistent. She also found herself to be moodier than usual. One thing everyone knew about Erin Lindsay was that she liked control. But no matter what happened that week, she felt as if she was drowning in a black hole, unable to grasp reality. She would be happy one moment and pissed off the next, her nostrils flaring and eyes on fire. Naturally, Jay noticed, his face full of concern when he approached her in the breakroom. But she snapped at him too, only to kiss his cheek when she noticed the hurt flash across his face.

She managed to sneak out of the apartment while Jay was at the gym. They had finished work early that day, which was unheard of for the detectives in Intelligence. But it had thankfully been a slow week full of paperwork before Voight sent them on their way, telling the team that he'd call if he needed them.

Erin made her way through the still snowy streets of Chicago to Target around the corner. It was Valentine's Day the next day and she hoped and prayed that the criminals of the city wouldn't foil her romantic plans of dinner and telling her husband the greatest news he would ever hear. As she pulled into the parking lot, she found herself resting her right hand comfortably over her abdomen, still toned and tight, no sign of any baby. But it was there. A smile subconsciously grazed her face, and her emotions had tears pooling in her eyes.

She was greeted by Valentine's Day decorations at the entrance of the store. There was candy and chocolate literally everywhere she looked and she found herself fighting the urge to march over and fill her shopping cart to the brim. Ultimately, she lost that battle as she piled four boxes of chocolate and three different kinds of candy into the cart. For the baby, she told herself.

Pulling herself away from the sugary treats, Erin moved toward the baby department, hoping something would jump out at her as the perfect way to surprise Jay. She had never really ventured into that section before; there had never really been a need, and it had always seemed so overwhelming. Honestly it still was—breast pumps and bottle warmers and scratch mittens and—what the hell was a snot sucker? Eventually she found herself looking through the seemingly endless collection of baby clothes. It was all so tiny and adorable and she started imagining a little person that was half her and half Jay nestled in her arms. Nothing could have stopped the smile that quickly spread across her face at that thought.

Finally, she found it.

Erin stopped on her way home to grab takeout from their favourite place. As she slipped into the apartment and locked the door behind herself, she could hear the shower running. Jay was home, so she quickly stashed her purchase in the back of her sock drawer.

When she heard the water turn off, she ran out of their room to cover her tracks and make it look like she was just busy setting up dinner. She scattered the boxes of candy and chocolate on the kitchen island before placing the takeout containers at the kitchen table along with plates and utensils.

Jay's hair was glistening wet from his shower when he joined her a few minutes later, dressed comfortably in a t-shirt and sweats. He stopped dead in his tracks when he noticed the assortment of sweets on the kitchen counter and questioningly raised an eyebrow at Erin. "Uh, when did you buy all of this?"

"I went to pick up dinner and I was craving something sweet."

"What, so you're saying I'm not sweet enough for you?"

She rolled her eyes, laughing at him. "You are such a dork."

He chuckled along with her as he rested his hands on her hips. "Yeah, but you love it."

Erin popped up onto her tiptoes and gave him a quick kiss. "Most days."

They made small talk over dinner, chatting about recent cases and making plans for the next day. Chicago was due for a late winter blizzard, so a romantic night out on the town was highly unlikely. Erin told Jay she just wanted to do dinner at home, nestled on the couch in front of the Blackhawks game. He didn't need much convincing; he wasn't the type of guy that liked getting dressed up for dates.

Little did he know she had other plans.

Erin woke early the next morning, her excitement for dinner that night was palpable. When she turned her head, she was greeted by Jay's sleeping face, his mouth slightly agape.

Smiling, Erin leaned onto her left elbow, placing her lips against Jay's parted ones. She kissed him lightly, sneaking her tongue into his mouth. She pulled back a little when she felt him stir underneath her, but was disappointed when he went back to sleep. This time, she put more force into her kiss, catching him by surprise. He lifted his head off of his pillow slightly and kissed her back once he realized what she was doing.

"Morning babe." She smiled down at him.

"Good morning. Sleep okay?"

"Mhmm." She placed her head back down against his shoulder and closed her eyes again. There was no going back to sleep once she woke up, but she would stay in the comfort of their bed all day if she could.

She felt Jay move and when her face was no longer touching his skin, she opened her eyes. Jay was sitting up in bed, looking over at Erin with a grin on his face and before she knew it, he was straddling her hips. He bent down and kissed the sensitive part of her neck that made her legs shake.

"Happy Valentine's Day, babe." He managed between kisses. Erin felt his hands roaming her body and stop at the hem of her shirt. She grabbed his hands as he started to tug on it, stopping him.

"Not now. Later tonight. We need to get some groceries before the storm hits." She heard him groan in frustration and felt him press himself against her. "C'mon, we gotta get goin'." Jay didn't budge.

"Erin, I think we should have a baby." Her heart dropped. He knows. "I know we've talked about it here and there, and it would definitely be a huge change, but… I know we can make it work. I think we're ready." Relief.

"Can we talk about this when you're not pinning me down and trying to seduce me?" Purposely, he pushed his bulge against her through their clothes. "Jay!"

"Okay, fine. We'll talk about this tonight. Maybe in between rounds?" He got up off of the bed and winked at her, heading towards the bathroom to shower. When she heard the water turn on, Erin let go of the breath she didn't know she was holding. Well that was close.

The day had been uneventful. They managed to make it back home from the grocery store before the snowfall got any heavier and they had stayed cuddled under a blanket in front of the TV for most of the afternoon. Jay offered to cook something for dinner that night, but all Erin wanted to do was stay on the couch, in the comfort of her husband's arms. They agreed on Chinese food from one of Jay's favourite places a few blocks away, calling the order for delivery since neither of them wanted to venture back out into the blizzard.

They settled back on the couch and waited for their food to arrive, just enjoying the peace that always came from being wrapped up in each other. Erin's stomach growled loudly, and was quickly followed by a knock at their door. Jay jumped up and ran to answer; he knew better than to get in the way of his girl's appetite.

When he returned, Erin was surprised to see that he wasn't carrying Chinese food. She beamed at the large bouquet of flowers he presented to her.

"Daisies?" Her hormones were already going haywire; it took everything Erin had to stop herself from crying. Instead, she flung herself into Jay's arms and kissed him softly. "Thanks love."

As they were pulling away, they were interrupted by another knock. Jay grabbed the food and brought it over to the coffee table. Wearing sweatpants and hoodies and eating Chinese food in front of a hockey game wasn't what most people imagined when they thought of a romantic Valentine's Day. But for Erin and Jay, it was perfect.

When they finished eating, Erin announced that it was time for her to give him his present. Instead, Jay surprised her a second time when he told her that he actually had another gift for her. Again she fought the tears that sprang to her eyes when she unwrapped the small box to find a beautiful pair of earrings. They were just her style, understated enough to wear on the job, but elegant enough to make her feel special.

Erin was nervous as she handed him her gift, her eyes not leaving him as she watched him tear off the red gift wrap to expose a thin white box. When he lifted up the lid he was greeted with red tissue paper. There was something written on the lid and he placed the box down on the coffee table to read it. Erin watched anxiously as his eyes darted over the perimeter of the lid, waiting for him to react. "What does it say?" She asked softly, smiling.

"Happy Valentine's Day to a… DILF? D-I-L-F? I don't know what this means…?"

"You're serious, you've never heard of the word DILF?" Erin would have laughed at his confusion if she hadn't been so consumed by her nerves.

"Yeah… I don't get it."

"Open the rest."

Jay pulled the tissue paper back carefully to reveal a small piece of white fabric. He froze as he picked it up, clearing his throat to rid himself of the congested feeling he was getting. "Is… is this for real?" His question did nothing to squash Erin's nerves; she was afraid to speak, instead just nodding in response.

All of Erin's nerves washed away when Jay gently grabbed her face in his hands and leaned in to kiss her; she could feel his smile against her lips. "So you're happy about this?"

Tears were clouding his vision and his emotions were getting the better of him when he finally spoke. "Baby, I promise you I have literally never been happier in my entire life." The tears ran freely from Erin's eyes as he once again brought her into his embrace. She wanted to blame the hormones, but she knew that they came from her conscious emotions. Jay pulled back quickly, catching her off guard. He had a look of concern on his face and it made Erin's heart hammer in her chest.

"Wait, we can still have sex tonight, right?"

She playfully swatted his shoulder. "Actually funny you should say that, because… 'DILF' means Dad I'd Like to—" Erin was interrupted by Jay's lips meeting hers in a searing kiss. As the blissfully happy couple moved to their bedroom, the "Daddy's Best Backup" onesie temporarily forgotten on the coffee table.

When they had whispered words of 'maybe one day' all those years ago, neither Erin nor Jay had any idea that that moment would lead to something this wonderful.
