It'd been established very early in their relationship that whenever they weren't working, Sunday mornings in the Santiago Peralta household were made for sleeping in.

It was a little habit of theirs (initiated by Jake himself) to enjoy their time cuddling in bed in the dark of their room until the sun was shining high outside, blinding them through the curtains and forcing them up and out of the room. Sometimes, one of them would maybe surprise the other with some homemade breakfast in bed in a pure act of romance and want to please their other half, which often lead to some grateful morning sex.

At least, it was the case until they welcomed a new member inside their family. As soon as little Ana Santiago Peralta came into their lives, the whole concept of resting became a long lost memory. Being woken up at ungodly hours of the night by the newborn's piercing cries had to be their new normal.

Still, neither Jake nor Amy would trade being parents for absolutely anyhing in the world – not even one well-deserved Sunday morning in bed, just the two of them.

Little Ana's presence in their life is more than enough to make up for their lack of sleep.

She's 9-month old when Amy has to leave her husband and daughter behind for a whole weekend for the first time. She doesn't want to, but doesn't really have a choice either – she has a presentation to show on a Sunday morning at a police convention out of state. And it's something she can't miss, it being another step towards her goal of making Captain someday.

She wakes up around 5:30 to go through her presentation one last time and make sure she's ready despite having spent what must have been one of the worst nights of her entire existence (if you don't take into account the nights she had to spend without Jake while he was in Florida or in prison). She finds it hard to get some rest when she's so far away from her beloved family.

She still manages to wake up early, though – her body's used to the lack of sleep now.

She sits on her bed and turns on the bedside lamp. It takes her a few seconds to adjust to this new light but as soon as she does, she grabs her computer and opens it on her lap to look at the PowerPoint she perfectly put together. She starts to read through it, but soon realizes it's hard to focus on her work.

Everything's calm around her – too calm, even. She hasn't been used to this kind of silence in months. And, instead of helping her put her attention solely on what's on her screen, the quietness makes her thoughts linger towards New York City and what's happening at home.

What Jake and Ana are doing.

Is she letting him sleep a little, or is it one of these regressive nights she seems to be having lately, unable to sleep correctly anymore?

Amy feels a little guilty she left him to take care of their increasingly energetic and curious 9-month old alone. He's the one who insisted she should go though, when she was about to decline the offer.

She truly found her right person in him, because not only is he a perfect husband, she also discovered (never doubted so) he's the perfect father too.

Still, she misses her family and wishes she could be waking up by their sides right now and not alone in this hotel room. Luckily for her, she has a way to see and hear them. It's an idea Jake and she got from an old case they solved together – back when they were no more than two coworkers fighting over who was the best detective. They turned one of their daughter's decorative teddy bears into a monitor and had Gina make the IT guys below their floor at the precinct connect it to their personal phones and iPads so that they can check on her wherever they are.

(It's crazy what technology can do nowadays.)

It was very useful for Jake when he first had to go back to work after his paternity leave ended and he couldn't bear the thought of missing on any of Ana's first months into this life.

Right now, it's Amy's turn to be grateful for it as she turns on the device, ready to sneak a peek on her baby girl. She frowns when she notices the bed's empty. She doesn't have the time to wonder nor worry about it though, because only a few seconds later Jake appears into the frame, holding Ana close to his chest as he rocks her.

Immediately, a smile forms on Amy's face.

"You miss Mama, uh?" His voice is sleepy and she can see him fight back a yawn. "I know, me too. I don't really sleep well without her either. But she's being a total badass right now. Well, actually, she always is," Jake starts rambling. Every new word he lets out warms Amy's heart a little more. In his arms, Ana listens to her father with her big brown eyes staring right at him.

Damn, she misses them as well.

"She's done a lot of badass things," he goes on. "Like, I know I always tell you about how great your Mama is, but did I tell you of the time she caught a bad guy while wearing a wedding dress? I wasn't there, but I wish I were. She told me about it, and Rosa told me about it. And apparently it was amazing. But I don't doubt it. She's an amazing Sergeant. And she's gonna make an even better Captain."

Her eyes are starting to get teary and blurry with the emotion but still, Amy can catch Jake's dreamy beam as he speaks so highly of her to their daughter. He's pacing around the room and bouncing Ana in hopes to lull her back to sleep with his movements and stories. It doesn't seem to work though, as she's still looking at him with her eyes wide open and wide awake.

Her tiny little hand is curled around the hem of his hoodie.

"You're really not gonna go back to sleep, uh?" He seems to think the same as Amy does. "Okay, I have an idea. What do you say we send her a good luck selfie? I'm sure she's already awake and working on her presentation and it could be a good distraction for her," Jake suddenly reaches for his phone in his pocket. He carefully holds the baby with one hand while he unlocks the device with the other. Amy watches him do from her own screen, letting out a small chuckle at the scene.

He knows her so well.

"For Mama!" he says then shoots a huge grin at the camera for a second. He takes a beat to look at it – Amy can tell from the look on his face Jake's satisfied with it. "Look how pretty we are!" He shows it to Ana and kisses her on top of her head with enthusiasm. The baby squeals in his arms.

It's utterly adorable.

Both of them are.

And she's sure they are beautiful in the picture indeed.

(She can't wait to receive it, even though she saw them take it 'live.')

Amy could keep watching them for hours but unfortunately, Jake talking about it reminded her she has to go back to work. The quicker she's done with her presentation, the sooner she'll be by their sides, she tries to tell herself as she unwillingly turns off the monitor on her phone and goes back to her PowerPoint. It doesn't take long before she's distracted again though, when she receives a text. A smile forms on her face before she even glances at her phone – she doesn't need to look to know who it is, and what it is about.

Jake Peralta:

We miss you. Can't wait to see you tonight. You're gonna ace this presentation xx

She reads the message accompanying the (really cute indeed) picture with her heart full of love. For sure she can't wait to see them later as well.

Thanks, babe, she writes back. I miss you guys too. So much.

(And for the record, I think you're an amazing Detective too.)
