I heard that everytime you drink while pregnant that it kills some of the babies brain cells. Thats why the say dont drink when your pregnant.
There is a chance that they baby might be diagnosed with Fetal Alcohol Syndrome...It's a hard thing for parents and the child to deal with. It comes with multiple learning disabilities and some physical abnormalities. Some people drink the entire pregnancy and nothing happens to their child and another women can drink just one drink while pregnant and the child is born with FAS.
