Behaviors during pregnancy: can have a serious impact. Pregnant women who use alcohol or other drugs greatly increase the risk that their babies will be born with mental retardation, low birth weight, or fetal alcohol syndrome. factors that causes mental retardation.

Rubella infection: during pregnancy puts the baby at risk. Immunization against rubella either during childhood or in the first three months of pregnancy reduces this risk.
