'Little evidence' that light drinking in pregnancy harms unborn babies

"A precautionary approach is still reasonable, but with luck this should dispel any guilt and anxiety felt by women who have an occasional glass of wine while they are pregnant."

There is very little evidence that light drinking in pregnancy harms unborn babies, a review has found.

The study found an association between light drinking and smaller babies at birth but found no evidence of other harm, including miscarriage, birth defects, developmental delay, behavioural problems and impaired intelligence.
