My ex-wife was the secretary to the chief of Obstetrics at the Ottawa Hosîtal for many years (who delivered the children of every prominent person in Ottawa including the Trudeaus)
Having witnessed the effects of Foetal Alcohol Syndrome with expectant mothers who drank even only small amounts at critical points in foetal development, she NEVER touched a drop during her pregnancies. My sister on the other hand continued to drink through her pregancy. Her son is a handsome young man, who is unable to speak clearly at all (at age 20), has rage issues and varous subtle developmental delays.
The real tragedy is we all recognise it, know she was entirely to blame for it, but the rest of the family pretends it is normal that a kid his age cannot speak intelligibly at all. I could never understand him through the terrible slurring.
He has no social skills and eats soap.
(I wish I were kidding)
I made the mistake of pointing out in a private conversation with my Mum about his speech problems and seeming autism (which was their theory at the time) that he exhibits classic symptoms of FAS (and and that my sister drank throughout her pregnancy) For some reason my Mum told my sister what I said and she freaked out on me and has never spoken to me since. Guilt, I assume.
He was mocked cruelly in school because he spoke like a baby. (unable to form many sounds) His lingual development is just not normal. So he could stand up for himself she enrolled him in Karate - where he earned his black belt.
But he is good with plants. He will talk to them for hours.
