He doesn't like the learning aspect of school as he struggles, but he loves his teacher and the assistants. He gets invited to all the kids' parties and goes to them all, and joins in. He has been away with the school and loved it, so I don't think there are any problems there.... apart from him hating the actual work!
I think its because he is the youngest of my children - he's 8 (but comes across as younger) and his brothers range from 12 to 19, so I think he favours adults, as that is what he is used to He sees his 19 and 17 year old brothers, and their friends, as "adults", so I think its normal for him to veer to older people, rather than play with 8 year olds in the playground. At home he is always with his 12 and 14 year old brothers, so I think he might find the games of 8 year olds as being "too young" for him.
