I am a retired school administrator, and I strongly suggest that you meet with your son's teachers and school principal to discuss his condition. Most schools have one or more students who are diabetics, and you need to be sure they understand your son's particular condition and their role in insuring his needs are met while he is in school. If his school has a nurse, so much the better, but everybody in his school setting should be aware of his particular needs.

Also, I suggest you obtain some kind of medical identification bracelet or dog tag that identifies him as a Type I diabetic and that has emergency contact information. I wear a medical ID dog tag that I had made by a company that specializes in dog tags. It is red with an appropriate medical symbol on one side and medical details on the other. It was much cheaper than the specialized tags available from Medic Alert and others.
