I have a 4 yr old child with severe brain damage who is non-verbal and non-mobile. She is in a wheelchair all the time pretty much. She does however also have a seizure disorder which can be caused by overheating and / or dehydration. She is not the best child for getting fluids in top either. How do I get a card-thing to let us wait in the shaded areas. We are going May 13-May20th. Does she even qualify for this? And what is it anyhow?
