Which is more babyish?

Ok kids do you think a pacifier or thumb sucking is more babyish to you? to me i think sucking my thumb is alot more babyish to me but i like a pacifer to sooth me to sleep every now and then. but i have noticed if i fall asleep with a pacifer in my mouth it drops out sometime overnight, but if i suck my thumb i usaly wake up with it still embeded in my mouth and wet from sucking on it weird but true for me
