It sounds like he was about 8. There's no cure for fetal alcohol syndrome.
It's unconscionable for the adoption agency not to fully disclose a child's problems.
My nephew and his wife adopted (at great expense) a Russian baby when he was 1 year old. He was a beautiful child and seemed just fine until a couple of years ago when behavioral problems began to crop up.
Since then, he’s been in and out of counseling and temporary institutional situations. It’s been a very heavy financial and emotional burden on their family, especially his younger brother.
Naturally, there was absolutely nothing in the records to show his family’s mental health history, much less how he was treated in that orphanage for his first year of life. Very sad situation all around.
