A series of articles by Danish researchers found that when 1600 children at age 5 were tested for intelligence, attention, and executive function, there were no significant differences between children whose mothers had ingested small amounts of alcohol during pregnancy and those who had not. However, the authors still recommended that women should not drink alcohol during pregnancy, as no safe level has been established.
