Misty, I think Elizabeth had a good suggestion to try to observe your son at school. If you do determine that the fire drills are really the problem, can you find out from the school when they will take place? Since he is only 4, maybe he could just miss school that day or be taken out of school for a time so that he would miss the drill. You have to follow your mother’s instinct and do what you think is best for your child. Hang in there, it will get better! :)
