Gender disappointment?

Joni
I found out at 14.5 that I'm having boy #4 and at first I just felt happy that everything looked healthy. My oldest son was devastated because he wanted a sister so bad! I now have found myself hoping that the sono was wrong and I'm actually having a girl. But I also read on the ingender website people's stories of gender disappointment and I have nothing like that, just kinda feeling hopeful. Which I realize is pretty unlikely. I feel guilty in a way, and I don't dare tell anyone my thoughts and I'm not sure why!
