I'm also not finding out the sex but I often think about what I will lose if I have one sex over the other. I love the thought of DH with a son. This may sound bad but I see a difference in how he is w/ my step son vs my step daughter.... he loves them both equally but he loves having "boy" time with his son and his daughter is a pre-teen and drives him crazy. So I just see a bigger connection with him with a son. I, on the other hand, feel like I will lose out without having a daughter.My sister has 2 sons and no girls so I even feel a little pressure from her because I know she would love for me to have a girl to "share".
I think for most of us, who consider this pregnancy a miracle, feel this is very likely going to be our only child... and therefore it's probably pretty normal to have these feelings.
