I think it is important that you do not make a big deal about using the bathroom at school. The last thing you want is your child be afraid to use the bathroom at school, that will start a whole new set of problems! I agree with the other mom who states that you do not want your son to be wasting class time in the bathroom. I would remind him to go potty, wipe and return to class as soon as he can. I used to teach in the public schools, and it was a problem when the kids would take a long time to use the bathroom. He may miss valuable information.
