Dear J.,
I have no advice for you, but I am laughing as I read this. It has reminded me of a story my mother loves to tell of the time I was four and we were visiting her VERY pregnant friend. She was complaining (on a hot summer day) that she couldn't wait for the baby to be born. Apparently, I told her to just unscrew her belly button and let him out. Unfortunately, I can't remember how my mother explained the real way babies came out at that point, or I would pass that on along with the giggle. Enjoy you children. :)
