A new study has found that pregnant women who drink as little as one glass of wine a week could run the risk of lowering their child's IQ.
The University of Oxford studied the affects of alcohol on more than 4000 mothers and children.
They found children whose mothers drank one or two glasses a week scored slightly lower on IQ tests than those whose mothers drank nothing at all.
The study has once again stirred up debate over safe alcohol limits for expectant mothers.
