"Don't tell me you never changed a diaper before."

After Dawson and Olinsky arrived, the mission of nursing the little one through the first week at home had started.

Overwhelmed by the news that Erin had to stay at the hospital for several days, Jay had decided to request help and with Hank staying at the hospital, he had called for the ones in the team that had children on their own that were already out of diapers.

"Antonio, he is my first and only child. Of course it's a premiere."

"You've visited birthing class with Erin, don't you?", the colleague asked, receiving confused views.

"Yeah, but this is not a plastic doll. It's a baby. A real human- being."

"Okay, it's simple. You just put the piece under his bottom, then you have to close the stripes and…"

Olinsky couldn't end, because it was already too late.

Antonio started laughing, because Jays face was full of pee.

"…and you have to know that boys want to show what they can, as early as possible", the father of two explained.

"Now you have to finish by dressing him."

Jay looked at Olinsky, totally helpless.

"Can you stay the night?"

Both cops giggled like teenagers.

"Come on, guys. I'm drowning here. It's not funny."

Jay took the baby back on his arms and rocked it carefully.

"Never shake him. There is something called shaken baby syndrome that can cause you a lot of trouble. Always remember: It's not a six pack of beer"

"Trust me, a baby is the last thing I would shake", Jay looked at a beer on the counter. For a short moment he couldn't help but smiled.

But he got more serious with looking in his newborns face.

"You have to feed him every 3 to 4 hours. Even if it means waking him up. Since Erin isn't able to give him milk, you should use formula. Crying, moving his head from side to side or placing his hand, finger or fist to his mouth will show you that he might be hungry", Olinsky taught him.

"It's easy. It's always the same rhythm at the beginning. Feeding, sleeping, diaper change. Same things in a row, bro. And don't forget about body contact. It's important to calm him down by letting him know that you're there. This age is vulnerable. You won't catch up what you miss at this time."

Jay looked even more pale than he already used before.

"Come on, man. You're catching the worst guys in chicago. You can do this", Antonio patted his shoulder.

"I mean, look at this little boy. It's your son. Something that will always connect Erin and you. Forever."

The baby started to cry, so Jay instinctively started to whisper words of comfort until Terry stopped whining.

"See? You're doing a good job. Be a little more confident."

Olinsky and Dawson already went to the door, when Antonio stopped in the middle oft he way.

"Tip from an old father: Try kangaroo care."

"How do I do that?"

"It's a technique that is practiced on newborn wherein the baby is held skin-to skin with an adult. The only thing you have to do is to put your shirt off and let him lie on your chest. He's just wearing a diaper. The vestibular stimulation from the parents breathing and chest movement, the voice and natural sounds of breathing and you heartbeat and the natural tendency to hold him leads to positive effects."

Olinsky looked at his colleague in surprise.

"Wow, didn't know that you're such an expert."

Antonio smiled and waved goodbye before he followed Alvin outside.

Two hours later Terry was lying on Jays bare chest.

His little fingers touched the detectives skin, while a blanket was wrapped around both, avoiding that the newborn would become cold.

Jay kissed his baby boys forehead, proudly looking at the little bundle, that was snuggling on his shoulder.

Mouse was watching the whole scene and smiled like a little kid that got to see Santa Clause for the first time.

"He looks really happy. Seems like Dawson was right. He's enjoying body contact."

Jay grinned, running his hand through Terrys hair gentely.

"You should sit here for the rest of the day. Neven seen him more relaxed during the last hours", Greg whispered, getting a serious sight from Halstead.

"I'm spending my time in this rocking chair since over 30 minutes. My whole body is fallen asleep and I start to get cramps in my legs and arms. If you put me in here for 24 hours, I might be ready to shovel my own grave."

"Come on. Look at this little face and you forget about all that", Mouse joked, carefully stretching his hand to touch Nathans small fist.

"Dude, these fingers. Tiny as a doll. How are you changing his diapers? I would be getting a panic attack."

"Trust me. If you would see me sweating you would know better."

Jay looked down on the little boy that protested by crying when he stopped caressing his head.

"Only 7 days old and such a bad ass", Jay smirked, continuing to stroke his hair, when his phone rang.

It was an incoming message from Erin who replied to the photo he had sent her. It showed him and Nate trying kangaroo care.

"I love you. You two are the best that happened to me", he could read as a text message…

"Forever Terry, you and me."
