Me, nursing the baby: Ow! Ouch! No! That's not nice!
Peanut: What did he do?
Me: He bit me.
Peanut, giggling: Where?
Me: My boob.
Peanut, still giggling: He did?
Me: Yes. You did the same thing when you were a baby.
Peanut: I did?
Me: Yes. And do you know what I did to you?
Me: I smacked you. Right on top of the head.
Peanut: You did?
Peanut, glaring: Ow. I hate you.
