Not sure if I am a little?

I've just recently learned about this so I'm not sure but I call my boyfriend Daddy when we have sex but I want to call him that all the time but I'm too shy. I don't think he knows about DD/LG or anything like it.

I have a stuffed bunny I had when I was little and I always sleep with it now. It makes me more comfortable. I love when he calls me baby girl, his little baby, little girl. When he does little things to make me comfortable or take care of me. I color sometimes when he's playing his game. I just love being taken care of if that makes sense. Treated like a lil princess. It does turn me on and also helps with my bad anxiety when I act "little" around him. But I feel like I don't do enough "little" things to be a little. There's not much more I'd like to do. I do like when he holds me like a baby and I looovveee his hugs and lil kisses and forehead kisses.

There was one time when a situation came up and he asked if I wanted to act like a baby (in a nice nouturing way) and I nodded yes and he was like awww my baby and hugged me so tight. He did say okay but he said I needed to act like an adult when I need to. I have 3 kids by the way so it makes it a little harder to have my time.

What should I do? Am I little? Am I something else? How do I bring it up?
