I don't think they would allow him to be in the room, so I don't think he'll be around for the childbirth. He knows where babies come from. We squared that question away. His response was "Ewwww." It is just the sex part that we left out.

Oh, BTW, we recently got on the subject of breast feeding. He was sort of shocked about it and I told him that I'd breastfed him. He got all embarrassed, then after a few minutes of thinking he goes "No you didn't. I totally remember. I am totally sure you didn't. You must be confused mommy." He was trying so hard to convince me that he wasn't breastfed. lol.
