Does anyone know of any other child with AS who also has the problem of being below weight/having very little energy/....I am asking for a friend who has a 5 year old with AS. He is eating (tho' restricted diet) but doesn't have the energy to play/wants to sit in the buggy all the time/gets tired walking up stairs etc. Any advice would be appreciated as this is now becoming more of a concern that the AS. He is having food with iron in it and the dietician has looked over his diet and said it is ok. Any idea's
