Thank you for your question. First of all, we tell all women that there is a background risk for having a baby with a birth defect of 4-5% (everyone’s risk).
Alcohol is a recognized human teratogen that, when consumed in large amounts, has been consistently associated with an increased risk for Fetal Alcohol Syndrome (FAS), a characteristic pattern of birth defects and development delays. Full blown FAS is seen in women who drink heavily (5 or more drinks per day) throughout their pregnancy. However in your case the amount of alcohol that you may have been exposed to when you ate the cake is minimal. Based on this exposure we would not suggest an increased risk for FAS.
If you have any further questions or would like more information, please call us at 1-800-532-3749 during normal business hours.
