My 11 y/o has recently started sneaking food and not covering with insulin. He wears a CGM, so it doesn't take long until I realize why his graph looks like Mt Washington and confront him. I have told him repeatedly that if he wants to eat snacks that it is fine (within reason) but that he has to give himself insulin or ask me about dosing. His excuse is always "I forgot". We do not have weight issues- he's at the bottom of the curve for weight and height. We are 3 1/2 since diagnosis and in general he is pretty receptive to his care (wears pump, CGM, can calculate carb factors etc). But it is nearly impossible to try and establish a trend in his numbers and make adjustments when this happens on a almost daily basis. How common is this behavior and how have you approached it?
