My son is 10, I was 42 when he was born, he has a 14 year old brother who is a great brother, caring and sensitive. My 10 year old is really comical, adorable, smart, but has awful anger issues. He is not from a split home, his father and I are married and live together. He also has Klinefelter's Syndrome. This was diagnosed through a pre-natal amnio test (due to my age). The Klinefelter's isn't obvious by any means, though he's pre-puberty.
