Nat said "Mummy and I need to do something special tonight... something just for us"
Kiya said "Watch a movie?"
I said "Maybe."
Kiya said "Go to bed and cuddle?"
Nat and I grinned, and I said "Or something like that"
Kiya said "Make a baby!"
I didn't know what to say, I was laughing so hard, it was so unexpected! Nat thought it sounded like a good idea, and Kiya matter-of-factly informed us "I want a little sister."
