"You don't have to do that, you know?" Jacey said, trying to find a towel to put over Spencer's shoulder. Spencer nudged his shoulder against hers, gaining her attention.

"I want to." Spencer said before getting out of his seat to bounce Mia around gently as he patted her back.

Jacey watched the scene in front of her, admiring the love Spencer had for Mia. She realized then that she was one lucky girl. And Mia was a lucky baby to have Spencer in her life.

...The Next Day...

Mia was crying, her face turning red. She kicked her little legs, not liking one second of having to have her diaper changed. Spencer struggled with keeping the baby calm and making sure she was clean.

"Almost done, ladybug." Spencer told the baby, trying to match his volume with her cries. Spencer quickly fastened the fresh diaper on Mia's small waist.

The infant calmed down instantly once she was in Spencer's arms again. "See? Told you I was almost done."

Blue eyes watched the genius, Spencer couldn't help but grin at the tiny human in his arms.

"She didn't give you too much trouble, did she?" Jacey asked, coming out of Mia's room with her baby bag ready.

Spencer shook his head, his eyes shifting to the mother. "No, she was fine."

Jacey smiled. "Okay, well, it sounded like World War III in here."

"I don't think she likes having to get changed."

Jacey shook her head, amused at Spencer's comment. "Nope. I think the calm days are over, from here on out she's going to be loud and sassy."

"I agree with you. She's starting to figure out the routine of how things go. She cries, it's mommy and Spencer to grant her wishes. This behavior is common in babies her age."

Jacey crossed her arms, smile on her face. "How long have you been reading baby books?"

"When JJ was pregnant with Henry, I read a lot books on child development and what to do during childbirth."

Jacey nodded before picking up Mia's car seat. "That's really nice of you to be prepared like that. You are so incredible. Everyone is lucky to have a friend like you."

Spencer blushed. Just being under Jacey's gaze sent warm tingles in his stomach. "Thank you, Jacey. Means a lot."

"No problem." Jacey said, sending Spencer a warm smile. "You can put her in the car seat, we should be heading out anyways."

Spencer gently placed the infant inside her car seat, buckling her up shortly after. The genius grabbed his bag and Mia's car seat. Jacey grabbed her baby bag, which also had her valuables in it as well. Before leaving, Jacey grabbed two pop tarts, one for her and one for Spencer.

The doctor's office was cold and packed with other parents and their babies. Spencer and Jacey sat beside each other with Mia placed on the floor in her car seat.
