"Do you love ME forever Mommy?"
"Yes, sweetheart, I will love you forever, I'll like you for always, as long as I'm living, my baby you'll be."
"Why will I be your baby forever? I'm not a baby!"
"No, you aren't a baby anymore, are you? You grew and you grew and you grew, just like the boy in the story."
"But I was a baby? And I was in your tummy?"
"Yes, you were!
"Why was I in your tummy?"
"Because when a Mommy and a Daddy want to have a baby, that's where the baby grows until it's big enough to come out."
"Can you have another baby in your tummy?"
"Yes, I think so. Do you want a baby to come out of my tummy?"
"Yes please. I want a sister."
"Well, maybe you'll get a sister, but maybe you'll get a brother. We don't get to pick. When the baby comes out, it's a big surprise whether it's a boy or a girl."
"It's a big surprise? Like at Christmas when Daddy's present was a surprise and we couldn't tell him what it was?"
"Yes, just like that!"
"But…I want to pick. I want a sister."
