Can someone tell me about Little Play fetish?

So I’ve recently been chatting to an older man who I’m interested in. But he’s very intent on calling me baby and have me crawl next to him and do things for me (sexually). He’s dominant and wants me to be his submissive, but in a Little Play type of way.

Can anyone shed some light on their experiences with the Littles kink?

Also, what turns someone on whose a Daddy?
