It might be because when one of her eggs drops, it's always a boy when a boy's sperm gets into it, and when the girls drop, you're not prepared for her!!!! I hope this helped, and please don't get grossed out by it!!! Thumbs up if you think it was a good answer, and follow me if you think it was logical!!!! THX!
Well Christians will consider them as blessings, but science will consider them differently. Scientifically, what determine a child's gender are the chromosomes. The father is the main dependent of the child's gender, if the father supplies X chromosomes it will be a girl, but, if he supplies Y chromosomes it will be a boy.

sometimes women find out that their baby is not the one that they had excepted or desired. This can be very upsetting that the daughter you dreamed of is really a son or that your strapping young son is really a girl.
