I have a 15 year old son who has AS, he was lucky to get a diagnosis when he was around 3-4 years old. I hate it when someone says don't "label" your child, we had a real fight with his consultant as she wanted to postpone diagnosis and wait and see. I had to insist that he was given the "label" and if necessary we would peel it off later. I am happy to read that the other poster's child was glad to have his label!
He was lucky to attend a small primary school where my wife is a teacher. The whole school knew him so he got on well at school. He is a bright boy but he is stubborn and he only does the lessons he likes. Well he does all of them but only gives minimum effort to the ones he dislikes!!
As already mentioned, it is important to talk with him about anything and everything. That way you will be able to pick up on what makes him tick - please don't think I am being condescending or suggesting you don't speak to him - I simply mean involve him in as much as you can.
We found that it was helpful if we did a lot of "what if" talks with our son so he could prepare for events. He has a poor feedback mechanism so he doesn't always learn from events. The more you do it the easier it becomes and slowly you will hopefully find he starts asking you "what if?" That is a good time because then he will start to think more about his actions.
Have you tried any sports with him? We found he loved chess so I taught him that. He eventually went to chess club where his attitude and interest was shared so he made friends.
We also noticed he had a real love of water so we taught him to swim. He struggled at first but we discovered he hated getting water in his eyes. A pair of goggles solved the issue and he just enjoyed it so much. I have spoken to other parents with AS children and they also found their children liked the water. I think it is the isolation of the water or the feeling of being cuddled by the water. My son loves it and is now a very good competitive swimmer. This has gained him real sporting recognition at his school and his self esteem has risen so much. He is as fit as a flea and rarely ill. He has represented his school at swimming and raised considerable sums for charity by swimming the UK channel distance in the pool.
As he gets older he develops more coping strategies for social situations but he also struggles with "small talk". His swimming means he has a strong toned body and the girls like him - he doesn't know what to make of this. I mean this in the best possible way, the girls are very good to him calling him "cute" and "a decent boy". Naturally I think he is the most handsome boy in the world but it's good that others agree
I hope that helps you, please contact me if you would like to know more.
