My son seemed to have a reasonable level of energy when he was younger. He has always felt the heat - turns bright red and sweats a lot. His energy levels are very low and he has very low stamina but always tries very hard to join in. He is salt wasting - I think each child is different - and I do feel it is part and parcel of his CAH. He is always exhausted after a day at school and he is always appologising for being ill because he doesn't feel well.
