Baby Y is now 7 weeks into development and is approximately the size of a Tic Tac and the weight of an eyelash - while this is extremely teeny-tiny it is approximately 10,000 times larger than it was at conception. Heck, even Granny isn't gaining weight at that rate!
Baby Y will remain "it" until early in October when Mommy and Daddy are hoping an ultrasound will determine the sex. Baby X did not have his sex discovered until birth but Mommy wanted a boy so badly, we just assumed Baby X was a "he".
This time Mommy's "sexual preference" is not so emphatic, but she would prefer if Baby Y is a girl. She has voiced this a few times - obviously within earshot of Baby X, because 2-year-old Xander woke in the night with a nightmare. When Mommy went in to comfort him he cried in his semi-comatose state, "No! I don't want to be a girl! I want to be a boy!"
