My son is 4 years old. Recently he was diagnosed with pervasive development disorder or mild autism. Currently he is not verbal much, he uses sign language when he wants something. He speaks alphabets, numbers, colors & rhymes. He was going to normal play school earlier but that time he was not diagnosed with autism. He could not continue going to school due to sleep issues. He used to do the activities in school but couldn't mingle with other kids & got scared seeing them. I wish to send him to school again. Shall I send him to main stream school or special school. Or shall I do occupational therapy besides sending him to normal play school. Please suggest.
