Baby Girls

We went to dinner tonight.  Nothing big and shocking there.  But as we are sitting there, E makes a comment along the lines of why does Jason always wave and notice all the baby girls around. (there was a table behind us with a big family and they had several girls at the table) Aaron says it is because Jason never had a girl.  My heart broke at that moment and it made me so sad.  I had been really ok with having a baby boy until that moment, and then, it took all I had not to burst in to tears at the dinner table.  I still want my baby boy, but I want so desperately to give Jason a baby girl.  I just don't understand why we can't have one of each...
