When my daughter had a concussion at school (also LPS), after they called me to tell me she had hit her head and was throwing up, I called her dr on my way to the school and they said to go straight to the hospital. I was very angry however when she was also asleep and not being monitored! I just grabbed her and went. When it was over, I just let it go. However, in other instances I have met with the principal to discuss concerns and that's what I would advise you to do first. Also working in childcare, we have quite a few children that if their temp gets to 99 we have permission to give tylenol/ibuprofen BEFORE calling the parent because of their risks for seizure. That might be something you could check into if you can have them do.
