I met a pregnant friend for coffee who shared that she had been crying on and off all week because she found out she was carrying a boy. I laughed because I thought she must have been kidding, and was told off for being callous...
When I told this story to a friend at work, she said it was common and shared that her husband sulked for days when they found out they were having a girl. 
Am I missing something? It seems really childlike to be disappointed over something that was only ever a 50/50 chance?
