His feet are a big problem, he wears boots most of the time as there's no other support for his ankles, he tends to fall over as his ankles just flop IYKWIM. His new school teaches rugby (not tag) for the Autumn term and has agreed that this isn't a good thing for him to do but he needs to do something. Running is a problem aswell as it's painful for him and his legs become very tired.
He does tag ruby at his current school (in his boots) so he's not knocked over. He is also taking pilates lessons outside school in the hope that it will improve his muscle tone but it's a long process.
