C.,
I know you have all ready received a lot of advice but I thought I would drop you a short opinion. My son (who is now 4) was mentally VERY smart. BUT, he just couldn't get the words out. Putting him in speech therapy was the best decision I could have made. He started it when he was 2 and by 3 he was into saying sentences. "I want milk" "Cookie please" and just a ton of short phrases. No more than 2 months after his 3rd birthday he took off with his speech and was saying complete sentences and words for anything he wanted. Not only did his therapist really work with him but they taught me a lot. I watched what they did and would work with him all week long on the same things. They also taught him sign language. So, until his speech took off he could communicate with me by signing. He could sign please, more, thankyou, eat, all done, play and just words that can make life a lot easier. It made my life so much easier. I could finally communicate with my son.
And, now that I have a lot of that knowledge I can understand other children and work with them much better.
Good Luck
