New to the board, and am starting to see tons of similarities from your posts in my little guy.
He uses 2-3 word sentences at 12 months, and is always on Que. when asked a question. His timing is amazing. He is very sociable and wants strangers to notice him.. if they don't he stares at them smiling until the do... He really won't leave them alone until they show him some kind of attention. He laughs to himself a lot, and seems to get things that other kids his age wouldn't understand.
He's very aware of everyone around him. Has a fascination for putting tiny ipod speaker cables ends into the little jack. The tinier the better...

So is speaking in 2-3 word sentences early a sign of giftedness?????
