DD walked at 12 months. She said her first word at 7 months and acquired more gradually till she had more than 50 on her first birthday. She had hundreds upon hundreds of words and was talking in paragraphs at 18 months.

DS walked at 13 months and said his first word at 10 months. I think he had maybe 20 words at a year, or soon after. His language development was slower than DD's, but still well ahead of the curve, especially for a boy.

DD has tested MG, though we suspect her score is a bit low. DS has not been tested. He is able to read beginner books at not-yet 4 (DD didn't read till nearly 5, at which point she suddenly read fluently) and is showing some other signs of being a bit "more" than we suspected. He is a much less driven child than DD, except when it comes to chess.
