Two things: first, be sure to have him evaluated by a pediatric behavioral health clinician, to rule out the presence of any neurointegrative (e.g., hyperactivity) or emotional condition; second, focus on the methods of behavior management you are utilizing. For an effective, tried-and-true behavior management approach, read Lynn Clark's book SOS Help for Parents. It will provide you with a practical, effective approach to handling your son's behavior.
I fear I will have the same problem with my 2 year old. How old was your kid when he started talking? Mine barely talks. I've had his hearing checked, but he hears fine. I fear my son may have a form of autism, have you ever checked into that? From what I hear, there are very many forms of it. Everyone tells me you can't diagnose until 4 years old. I try to get my son checked and they say he's too young to tell. I hope your endeavors with your child work out. I feel I am on the same road you are. -ering
He started around 2. He speaks very well for his age, even when he was three he was going on and on. He is very smart i think but just doesnt want to listen. I am planning on bringing him to a dr sometime soon to see, in case there is something there. I never had him checked for any type of autism, he was premature at 7 months, but seems to be very smart and remembers a lot of things. I just want to find out why he is so against listening and following tasks.
