It's ok for your son not to talk or only really say 10 words. My friends son just started really talking now and I believe he is 3. My friend had her son go through hearing tests and such. He was normal. My grandma's brother didn't start talking til he was 5yrs. I wouldn't push him into saying words. Just keep talking to him. Everytime you pick something up or doing something or point at something communicate it to him....milk, cup, eggs, dog, cat,please, thank you, your welcome, walking, stopping, red, green, I could really go on can I. I was with a friend the other day and she said that my son responds to one word commands....like "no", stop, down, up, and such. I have noticed that I keep it simple and short with him. I don't ask "Can you, will you, why don't you"....ect. Their minds and attention is short. So, I keep it short. So, when I say a word like dog and he repeats it back to me - I say that's right "DOG". So, if your son is not talking - it's ok. He's not ready to communicate. Back to my friend really quick though....with her son. He would point at his cup for instance....and kinda wine....or "Uh". She would get it for him automatically. He didn't need to communicate so, he wouldn't either. Well, I hope that this helps. I would like to hear how your son develops. No pressure...it will happen.
