You don't have kids, do you? After I got through with him, he would wish that he had never been born. If that child had died, that would be one hell of a, gee I wish I had a do over, I would have done things differently. I don't care how many time he had been played, not my problem. My child not being able to breath, that is my problem and would be his also.
I do have kids, and until I had children with this condition, I had no idea of how serious it can be. I'm glad I saw this thread - I've always told my kids that they have MY permission to leave class if they really need to use the restroom (after one child was ignored by her gym teacher, and I had to bring a change of clothes...). The nurse has their inhaler - they will always have MY permission to leave a class if they need it, regardless of what the teacher says.
OP, I would go to the teacher, explain how serious this is, and make sure your dd has her inhaler (I know I sometimes forget it, especially off-season). Even my DH has been too laid back, in the past, about this (I rememer ds12 calling me from the soccer field, stating that his brother couldn't breathe, and his dad was talking to the other parents, and I told him to tell DH to get in the car, and get home ASAP).
