Regular heavy drinking can cause miscarriage, stillbirth, and premature delivery. There can be withdrawal when the baby is born. This could make them trembly, very cranky, and cause feeding problems. In the most severe cases the baby could have seizures. Some of the lifelong problems they may suffer include emotional or learning disorders and a tendency to more childhood illnesses.
Neonatal abstinence is the name given to infant drug withdrawal.
The onset of symptoms may be present at birth or may begin within four days of delivery. In some instances, symptoms may not become obvious until 10 days of age. This depends upon the drug the infant was exposed to in utero, the duration of exposure and how rapidly the infant can clear the drug from their system. Some of the symptoms of narcotic drug withdrawal may last up to 6 months. They also have feeding problems.
