Fetal Alcohol Syndrome is a condition in which women who drink alcohol heavily during pregnancy, especially during the first trimester (first 3 months), have an increased risk of delivering a newborn with multiple birth defects. Typical physical defects include a small skull (called microcephaly), congenital heart defects and small eye openings. Additional newborn defects, which can develop as a result of the mother drinking later in the pregnancy, are delayed or retarded physical development, and mental retardation. A woman who drinks heavily during pregnancy has about a one (1) in three (3) chance of having a child with fetal alcohol syndrome. Our best advice is for women not to drink alcohol at all during pregnancy.
