The less alcohol you drink the better since alcohol passes through the placenta and affects your baby. No one knows how much alcohol is safe, but we do know that a high consumption of alcohol can affect your baby’s growth and can interfere with your baby’s ability to get enough oxygen and nourishment for normal cell development in the brain and other organs. Current guidelines say its safe to drink one or two units of alcohol once or twice a week but some experts advise cutting it out altogether.

Alcohol and pregnancy – One unit of alcohol is the equivalent of:

100 mls of wine (1 small glass)
100 mls of champagne (1 small glass)
300ml (1/2 pint) beer, larger or cider
1 pub measure of spirits
1 pub measure of sherry or liqueur
