Middle? Possibly?

Im 16 and im safely dipping my toes into BDSM waters with my Sir. Nothing hardcore but just tasters to see what we like. I’ve never really noticed it but sometimes I’ll focus on a certain toy or thing (like playing cats cradle) and it amuses me like I’m a small child. I get into this childlike mindset but I can still talk normally and process english properly

I don’t have the urge to toddle around but I get really giggly and find everything funny when I’m in this space, I also like cuddles and getting caring attention from my Sir. He doesn’t mind but this lack of label for it leaves me confused, am I a little?
