Someone around his age

Molly was getting ready to look after her latest charge while his mother went over where the essentials were. Just like Nick's mother, she had no idea about who the baby boy she was looking after really was.

Once Nick's mother left, Molly went to greet him. "Hey there, little guy. Your Mama's not here right now, but I'll be here to play with you for now." She cooed while pinching Nick's cheek, much to his dismay. Nick wanted to talk, but he knew it was pointless in his current state. Maybe he could sneak out and go on patrol once she was asleep. "I get it. You're cranky because you're hungry, aren't you? How about a nice ba-ba for you?" Molly offered, causing Nick's eyes to perk up.

One of the few things he liked about his current arrangement/curse was his daily bottles. He had no idea why, but whenever he drank one, he just felt so relaxed, as if he was an actual baby. Molly briefly left the room to get a bottle of warm for Nick, who eagerly got up to his knees in his playpen, reaching out with his arms and chanting "Gimme! Gimme! Gimme! Gimme!". All Molly heard from the little boy was his cries of "Ba-Ba!"

"That's right, drink up little guy." Molly picked Nick up with ease (possibly a side effect of his powers), and fed him the bottle. Once it was empty, Molly placed Nick back in the playpen so he could go play while she watched a movie.

Unknown to either of them, some people were plotting to break into the presumably safe house they were in...
