Boo-Boos and Boobies

Nora's teacher is pregnant. "There's a baby in there!" she says. Then sometimes she points to my boobs, which are (thankfully!) bigger than my tummy and says, "Baby in there?"
I say, "No, no baby in there."
She is very excited about her teacher's baby.

Nora has a boo-boo on her knee.
She is very excited about her boo-boo, but sometimes she calls it her "boobies."
"My boobies hurt!" she says.
"Where's your booby?" I ask her.
Nora points to her knee.

Recently Nora discovered the difference between her belly and her chest. She points to her tummy and she says "Belly!" and she points chest, just below her collar bone and says, "Chest!"

And then, tonight in the bath, she said, "Momma, you don't have boobies on your chest."

I thought this was a strange thing to say.
Did she mean a boo-boo? No, I didn't have a boo-boo on my chest.
Did she mean boobies? I have boobies.

I didn't know what to say, so I said, "Really?"
"Yes," she said, "you have boobies on your belly!"

Yes, I suppose I do. No thanks to you, my sweet Nora, no thanks to you.
