I knew a little girl some 30 years ago,who was born with this condition. The parents were asked whether they wanted the child to be a boy or a girl. They already had a boy so they decided to let this one be a girl. I have never seen a more boyish girl than her, should have allowed her to be a boy instead; she played only with cars and other "boy-toys", only with boys, she ran and behaved like a boy 100%. I wonder; is there no way to take bloodtests to see if the baby has more male or female chromosomes, to make it easier to decide what gender to choose in situation like these?

@lindaolsen7089 so why don't they take the dna in cases like this to check if the baby is male or female? Or does these babies not have any x or y chromosomes in their blood?
