OK so my son has had the dexcom sensor come off twice now when he was bumped while playing basketball. He has made up his mind not to wear it again until basketball is over. I tried to keep the discussion open by suggesting that he wear it on his stomach instead of his arm but unfortunately he already had it on his stomach. Next I suggested that he wrap it. He said that if it comes off under his shirt that wrapping it won't help. Anyone have any good ideas for keeping it on during basketball?
