I have been lurking on the board for a bit but have to respond to this one. Yes, people really are that stupid even family members can be that stupid and insensitive. It's especially hard to hear things like this when at this stage all you care about is 1. feeling like you aren't going to puke 2. that you are growing a healthy babe. For most of us gender is not an issue - we love the little bean we are growing regardless. When I was about 12-13 wks along with babe #1, we met my MIL for dinner. She seriously said "I hope you have a boy because [my son] really needs another man in his life. I mean, I guess if it's a girl I'll love it, too but I just really hope its a boy."
I could barely contain myself, I just laid into her about how her son having a son isn't going to replace him not having a father (one of her biggest hang ups in life, though he turned out just fine). That he has plenty of male friends, is close with my father and BIL. And she went on how my family is mostly women (me, my mom, my sister and my two nieces) and there aren't enough men (my dad, brother and BIL). It was all very offensive, illogical and insensitive. And she came up with all sorts of crazy reasons why a son would be better...Her next obsession was that my son not have brown eyes like his mom, but blue like her and her son. Needless to say, though my MIL and I used to get along just fine, that all changed as soon as I found out I was preg w/ my DS.
