The last time I posted, my son was 18 months and there was some concern about his word loss being a sign of autism. When we went to his 18 mo. check-up there was a check list screen for autism and the doctor believed that he was not autistic. I was relieved at that time. I am now convinced that my son is not autistic. Since that time my son has blossomed in his vocabulary. He's speaking somewhere in the neighborhood of 400-500 words. He says short sentences and reads around 6 word sentences aloud. The words I thought he had lost have come back plus many, many, many more. He still has a great since of humor. He loves to make us laugh and he loves to be tickled. He is very playful and fun to be around.
