Oh boy, I'll try to keep this short. My mom is the worst about "encouraging" my son to take his insulin or eat his snack by saying things like, "Eat (or take your shot) so you won't get sick" or even worse, "Let mama give you your medicine." My husband and I are very careful about the vocabulary we use. We don't tell him he'll get sick, but we will say he will feel bad. I don't ever call insulin medicine because that implies that he is sick. I don't even use the word 'shot.' I will say injection sometimes, but mostly just call it his insulin. I have tried to beat this (not literally) into my mom's head.
I can't stand it when I share with a family member, usually my mom or dad, what his BG is and they respond by telling me, "That's bad" or just saying "Trish!" as if I did something wrong. I never tell Brandan his sugar is bad or good. It's just right, too high or too low.
He has a long time to live with this disease and I won't let him think he's sick all the time. I won't let him feel like he's doing something bad or good based on the number on his meter, but I will teach him the importance of the numbers and how to use them as a guideline.
OK, I'll stop, for now. ;)
