I just had this conversation with Tim. We were lying in bed in the dark, and he brought it up spontaneously:
T: Hey, you got a baby in your belly.
H: Yep, it's going to get bigger...
T: Yeah, it's going to get bigger and bigger and it's going to come out and it will be a little baby.
H: The baby will be your baby brother or sister.
T: It will be my baby sister.
H: Tim, I think you'll be a really good big brother.
T: Yeah, I will.
A couple minutes later, as I was tucking him in and about to leave, he continued:
T: When the baby comes out from my belly, it will get bigger and bigger.
H: Um, the baby's in MY belly.
T: NO! The baby's in MY belly!
H: Uh... Okay, 'night 'night sweetie...
As time goes on, I think it will become obvious who is correct in this argument. :-)
