I'm planning for his Christmas and birthday presents. He now shows a real interest in books which he didn't do for a long time although I always tried to encourage, his attention span is still short (he is a busy boy but it's definitely getting better and he can concentrate on one thing for longer).
So the actual story on each page cannot be too long or complicated as he'll lose interest very quickly and just wants to move to the next page.
A book that he loves is written by Sue Heap - Mine. It's brilliant as he has a little brother and it's really helped him learning to share.
