We "Ping" too. The meter remote always travels to school with him along with the rest of his D supplies (glucagon, juice boxes, snacks, etc.) all in a little shark backpack that goes in his regular school backpack. I would not describe Daniel as super responsible--he actually has ADHD--but he's only forgotten his shark at school once. When he gets home, it's the first thing I check--is the shark here?? He even carries it with him in school when he goes to his "specials" (art, gym, music, etc.). I think it gets to be like a woman is with her purse--it's just something you don't leave behind!
