Literally. He won't go to sleep and every time I go into his room, he bends over and says, "spank a bottom?" I don't think he really knows what it means because he's never been spanked.
I really hope he doesn't start doing this out in public. I will probably be shunned from my mom's group.

Re: My child is asking to be spanked
We do "Free Spankings" and we playfully tap her butt. But OP seems concerned so that's why I say ask some questions.
He doesn't go to daycare. I imagine he learned about it at preschool. I'll mention it to the teacher but I just kind of assumed he got the phrase from another kid.
