According to the Doctor and all the literature I can find about when children should start talking, how much they should be saying at what age, Aidan falls within the average range. At the later end of it, but still average. However, compared to the kids we know that are his age, he seems to be pretty far behind. These other kids say complete sentences that are easy to understand. Aidan does say a few sentences, such as "Here you go." and "I see baby." He says Hi, up, down, kitty, bite, baby, hello, one, two, three, bye-bye, excuse me, and thank-you. He uses them all correctly, except for baby which he uses to describe other children or pets. He knows which way is up and which way is down. He counts one, two, three. He knows that letters are what you read and write. (He will point at the letters in a book or on a paper I'm writing on and says A, B, C.) He has been whispering since he was 16 months old.
Maybe he has just been focusing on other things, like learning how to climb and sleeping in a big boy bed. He is still bigger than average for his age, in the 75 th percentile. He understands almost everything we say to him. He usually follows directions, with 2 or 3 parts to them. He is very loving to us and to our pets. His favorite people outside of our little nuclear family are Howards cousin Jim and his wife Buna. We decided to call Jim "Uncle Jimmy" and Buna "Aunt Buna" as a respect kind of thing, like southern family's do with adult friends. He knows who they are when we talk about them. I don't know, maybe I'm just overly worried. Maybe I should just relax, don't try to push him or anything, I just keep talking to him about things, using the same simple words for things every time. I hope that by modeling the words he will learn them like he has learned to say "Excuse me." when he burps, and "Thank-you." when someone gives him something. Am I over concerned?
