I try to look at gender disappointment not as being disappointed about what you have but about grieving what you don't have. I would be really devastated if we never had a daughter. Doesn't mean I would love any of my sons less, but I have always wanted to parent a girl so I can see how someone could be upset they don't get to experience that.
However I didn't find out in order to deal with that, I found out because I wanted to be able to call my baby by his/her name, and bond with him as the boy he is
I wrote out the envelopes for my baby shower invites today. Just have to print them out and send!
