Me: Jane you need to talk like a big girl, you aren't a baby anymore.
Jane: There's a baby in your tummy.
Jane: The baby can't poop in his* diaper.
Me: Nope he can't, he doesn't wear a diaper.
Jane: What does he wear?
Me: Nothing, he is naked.
Jane: Oh he wears little tiny** clothes.
*Five and a half-ish weeks until we know if it is a boy or a girl.
**Jane demonstrates how tiny the clothes are with her fingers (about the size of a bean).
