My son does not have an aide for any of those activities, but he is in APE, not regular PE (and we have had problems with APE) and he is supposed to have someone watching him at recess. It is in his IEP and that gives me a leg should something happen and he was not being watched (a leg to sue that is). I am not suit happy by any means, but it is there job to keep him safe and those areas are a huge liability for them. THey need to understand this....
