There's also a large study showing that binge drinking in early pregnancy is beneficial for the child's IQ. But the only statistically significant result was if it was done in the first 2 gestational weeks which turns out to mean "before fertilization". However, there are so many confounding variables it's not funny. One interesting thing they controlled for was the mother's binge drinking habits because binge drinking mothers tend to have higher IQ than non-binge-drinking mothers.
