Drinking in early pregnancy is not associated with adverse effects in children, says new research, but Kiwi experts says the findings are no reason for pregnant mums to "pop the champagne".
Danish researchers have produced five papers looking at the effects of low, moderate, high and binge drinking on young children.
The papers, published this week in the journal BJOG: An International Journal of Obstetrics and Gynaecology, looked at the effects of alcohol on IQ, attention span, executive functions such as planning, organisation, and self-control in five-year-olds.
Overall, the researchers found that low to moderate weekly drinking in early pregnancy had no significant effect on their neurodevelopment - and neither did occasional binge drinking.
However, high levels of alcohol intake - nine or more drinks per week - was associated with lower attention span.
