We had a similar thing with our little girl when she started school, she too displayed autistic tendencies, but she seems to have grown out of them. I'll have a word with my mum, she is the Special Educational needs co-ordinator at the school where she teaches and is pretty clued up on stuff like this. There are comparison charts and questionnaires that you can fill in at home to see where abouts on the spectrum your child is. It might be nothing to worry about. I'll try and see what i can find out mate. What tendencies is he displaying? If you'd rather not put it on here, by all means PM me and i will speak to my mum later. Hope you get sorted mate, as i say hopefully its nothing to worry about.
