How does a Mother's Drinking Affect her Unborn Child?
When a pregnant woman drinks alcohol, so does her baby; through the blood vessels in the placenta, the mother's blood supplies the developing baby with nourishment and oxygen. If the mother drinks alcohol, the alcohol enters her blood stream and then, through the placenta, enters the blood supply of the growing baby.
Alcohol is a teratogen, a substance known to be toxic to human development. Depending on the amount, timing and pattern of use, if alcohol reaches the growing baby's blood supply, it can interfere with healthy development.
If a woman drinks wine, beer or liquor when she is pregnant, her baby could be born with FAS. There is no known safe amount of alcohol during pregnancy.
What if I am Pregnant and have been Drinking?
If you consumed alcohol before you knew you were pregnant, stop drinking now. Abstaining from alcohol for the remainder of your pregnancy can have a beneficial effect even on functions that might have been affected by earlier drinking. The sooner you stop drinking, the better the chance of having a healthy baby. You could be pregnant and not know it. So if you are trying to get pregnant or are sexually active and not using contraception, don't drink alcohol.
