This is kind of out in left field and your son may be fine with it, but the times that I have checked myself (for different reasons), Danielle has made comments like, "aww, 90, you are so lucky!" or "you are always in range, I wish I didn't have diabetes". Each child has their own temperment but something to just keep in the back of your mind after the experiment is over.
