So I have my big ultrasound this Friday!

I'm still not sure if I want to find out the gender. I'm leaning toward not finding out. But, Daryl wants to know so I think I may get them to tell him and not me. That way if I change my mind later he can tell me. Or maybe he'll let it slip.
Joey has been TOTALLY into babies and birth. We have the book "A Child is Born" which has tons of pics of babies in utero and some very graphic childbirth pics too.

She loves the book! Wants to look at it all the time!
So I'm wondering if maybe I should take her to the u/s? I do have baby-sitting lined up so that I don't have to. Daryl will be there to help out. Do you think I should take her? I think she might enjoy seeing the baby on the screen, and it may help her understand - or it may not. Is she totally too young to get the connection between what's on the screen and what's in my belly? Am I just asking for trouble by taking her? Thoughts or opinions? WWYD?
