To answer the Jack question, he usually says the baby is a sister. But, he also says that the sister is growing in HIS belly, along with a brother. It's just a sexless baby growing in my belly according to Jack. Most other people think the baby is a girl, including John & my mom. I have no inkling either way. I think I just assume it's a boy because I've already had a boy & that's all I know. (And, I love little boys!)
Jack has also told me that he wants the baby to sleep in his bed with him. If it keeps me from waking up a zillion times a night like I did for months with Jack, I think it's a great idea!
