My son has mild autism/social anxiety and has had behavior problems since before he could talk. He would not go anywhere near strangers, would not look at them and if they tried to talk to him, he would get mad & "sreech" at them. I had ECI come out & they said he seemed ok developmentally, but he was so young (2) and that he should be evaluated again later. Things got worse & worse. I could not put him in daycare, because he was very attached to me & like I said, he would have NOTHING to do with strangers. In the grocery store, if someone tried to talk to him, he would "screech" at them, sometimes throw his sippy cup at them, or even spit at them! It was horrible! I dreaded the day I had to put him in school, because I knew it would be a disaster. I took him to our pediatrician who had me fill out some questionaires about his behavior and then sent me to Depelchin's Childrens Center to see a therapist & psychiatrist. After a little time in therapy, I saw the psychiatrist and she diagnosed him with mild autism/social anxiety. My brother also had social anxiety as a child, but back then, (70's) they didn't know how to diagnose him and now, he is 36 and a complete mess, he is now Bi-Polar, manic depressive and ADD. He can't hold down a job and can't manage his own life and has just turned into a miserable person. SInce he has gone his whole life without treatment, he doesn't want to take medication, because he thinks he is perfectly normal!! I will NOT allow that to happen to my son!! The Dr. recommended Celexa, which I was apprehensive about at first, I mean, he was 4 yr. old!! Who wants to give meds to a 4 yr. old?? Once he started that medication, things changed DRASTICALLY! He started to ask me in the grocery store if I would go up to complete strangers and ask their names for him! He was checking people out, commenting on their cool shoes or baseball hats! Something he had NEVER dreamed of doing before. He was SCARED of people, he used to tell me "I hate people". When it came time for Pre-K (about 3 months after he started the meds in Sept. 09) I was a nervous wreck. Even though he was better, he still was very attached to me. So, before his school year had started, they had a tour of the school for Kindergarteners, so I called & explained the situation & they allowed him to tag along, even though he was going to Pre-K. He still acted like he did NOT want to go, he would get mad when we would mention it. I talked to him about it all the time. I had other, older kids talk to him about how much they loved school. When the 1st day came around, he didn't want to go in, he kicked & screamed and even hit one of the teachers who was trying to keep him from running back to me. They finally had a teacher get him away from all the other kids, teachers & noise and into his new (quiet) classroom where she showed him all of the cool things in there and he was finally able to join the others. He was very shy & nervous, but they said once he calmed down, he was ok. He wouldn't talk for a long time, but now he absolutely LOVES school, he talks about all of his friends and looks forward to it each day. I know the effects of leaving a child untreated and it doesn't have to be that way. It is such a shame that my brother has to live like he does. The change it has made in my son, brings me to tears. He is happy. That is the best feeling in the world. Your son will be upset when you leave him, but you need to talk to him alot about it. PREPARE him. I found that with my son, if I prepared him ahead of time, he did much better than just throwing him into the situation. If we were going to a family members house for dinner, I would say "ok, we are going to eat dinner & there will be adults & kids there. They will probably want to talk to you. You don't have to talk to them if you don't want to, but they love you & want to say hi. If you feel uncomfortable, come to me" He usually would just stand, holding my legs, but he stopped screaming, because he knew what to expect. So, read him books about school, DVD's have other people tell him stories about school .Take him to the school playground, let him explore there. He will be fine.
