Without sonography how could know child is male or female
Well giving birth tends to awnser that
old wives say if you cary the baby high and do not look preg from the back side view its boy . if you cary it low and look preg from back its girl
Amniocenteses, chorion villi sampling. But both come with risks.
if your stomach sets high its a girl... if its a boy your stomach sets low.
Lots of old wives tales about that but basically it was always a surprise. Its only in the last 25 years or so that its been possible to know for sure before birth.
