Seeking expert counseling is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help.
Your son is showing typical symptoms of those with developmental delays. You did not specify if the cause of this was a general developmental delay or was actually classified as being an autism spectrum disorder (such as Asperger's Disorder).
There are tried and true methods that you can follow.
Let me try to cover the field for you by recommending several books. I see you are online now.
Does he have a more specific diagnosis?
I saw that you began to type a response but then stopped. Can you be more specific about his diagnosis?
You have left the chat but I shall still recommend some books for you.
May God bless and protect your family.
