Our daughter is only 9, but on travel soccer etc. We have used stress doses in the severe heat on game days. Our school nurse keeps the cortef and solu-cortef. They do not stress dose. At any sign of illness they call me to check it out. Usually I buzz in to school and find she is just getting sick. By this age she really seems to know when she is getting sick. The heat does wipe her out more so than the other girls, but I don't want to pull her out of any sports. We do not do any full day camps in summer, because I don't trust programs without nurses. In this respect she is a little different than most her friends, but we try not to limit her as much as possible. It is just this year that she has become aware of how much heat and illness she can take.
