You are in the stone age dear. Down's syndrome is a chromosomal aberration that has absolutely NOTHING to do with alcohol consumption. It's more dependent on simply the age of the mother. the condition of her eggs with age or sometimes just the hand nature deals you.
As far as I know, science has never found a link to pregnant based alcoholic behavior and Downs. S##t happens.
Alcohol abuse is harmful to a fetus but Down's syndrome isn't the outcome.
Is it necessary for you to be condescending when you answer someone's post? and no, dear, (pat pat) ..I am NOT in the stone age. Unless you wish to refute every doctor involved with this case because you are some sort of scientific genius.. which I somehow doubt.
