hi there! Yes puberty was really rough for my control but it was very different 15 years ago. Back then I was on two shots a day and had no carb or correction ratios, pumps were also only used on select people over age 18. My doctors pretty much told me to do my best through puberty but seemed to almost expect failure, it was a mess. I didn't really hit me until mid high school that I really realized what I was dealing with. before then I would sometimes take my insulin late, or early, not eat, eat too much, which I think is similar to not bolusing now a days. I was just not there mentally or emotionally, my mind was elsewhere and I think that is relatively normal for children at that age. I just loosely did what i was told (the bare minimum at that) and went along in life almost ignoring diabetes (my A1c still usually stayed in the mid 7% range, but to be at 7 I must have fluctuated a lot because I was not in that tight of control). Finally in college I started to REALLY shape up and take full responsibility. I think it happens much sooner for most people though. I think that the pump will help him immensely if he isn't already on one.

Overall I would say do your best, and make sure he knows that it's okay to not be perfect. I mean make sure he REALLY knows that. I think one of the main reasons kids at that age ignore it is because they finally comprehend the damage it can do later in life and that scares the crud out of them. Let him know, and really believe, that this isn't a game of all or nothing, he doesn't have to give up because he makes mistakes sometimes, and he isn't 'doomed'. Just take it day by day, and accept your imperfections. :)
