Why 5-year Olds Don't Have Babies

Last night, Lyra asked me, "Mama, did you ever have a child?"

"No, not in my tummy I said. I do have a child, though. I have you."

Lyra hesitated, "We-e-ell, I was going to ask why I don't have a child. But I know. Because if a kid had a child, they would have to change their diaper and they'd say, 'Yuck, I don't want to change a diaper. That's poo. I don't want to see that! That's gross. I don't like changing diapers.' So, kids don't have babies, right?"

Hmmm, how to explain the biology of a girl's body?

Russell piped in to remind Lyra, "But when we're old, you'll have to change our diapers, Lyra. Even if you think it's gross."
