You are not the world's worst mom! You're the best! When I look back to how I was when mine were little I cringe!
One of our grandson's(age 9) has mild Aspergers and some of the behaviour is very similar to Tyler's. He can't cope with change, change to routine that has been planned etc. It has taken a long long time for his dad to accept it isn't all bad behaviour, his mum had accepted he was different and worked with him well, but it was getting worse. We had noticed many years ago some more odd behaviour such as he had to go on a certain route to school and touch certain things or he threw a paddy or wouldn't move!

A couple of months ago they received a letter from school saying he had been naughty in a maths class. Apparently he just wouldn't do the work and wouldn't say why. The teacher got cross. Joel just said he didn't know what to say to her as he didn't understand and wasn't being naughty. Last year's teacher understood him more, but this one was a new. The other week his mum tidied up his bedroom and he came home and tipped everything out and made it a mess again! They have had a few meetings at school and hopefully they have a few things in place to help him and the teachers. He isn't bad enough at all to receive extra help, which is good and bad. They are beginning to worry about the change of school in 2 years though.
