Studies show that pregnant women who smoke or drink alcohol may have a higher risk of having a child with ADHD.
Odd, we had some neighbors (of a somewhat white-trashy background). Woman had a little girl and was said to have stopped smoking ind drinking during pregnancy. Fairly quiet kid as far as we could tell.
Second pregnancy while we lived next door, she let it all hang out in her style, smoking and drinking. That kid sure sounded brain damaged, screaming and making sounds like a monkey.
