SHOULD PREGNANT WOMEN AVOID ALL ALCOHOL? “Indeed, a study published last year found that boys born to mothers who drank 1 to 2 units per week were less likely to have conduct problems and hyperactivity at the age of 3 than those born to abstainers. Girls of such mothers, meanwhile, were less likely to have emotional symptoms and peer problems. The children of moderate drinkers (consuming 3 to 6 units a week) seemed roughly similar to those of abstainers, but there was an increased risk of behavioural difficulties in the children of women who drank more than 7 units a week.”
