She needs to know if it is too low or too high. Normal blood sugar is between about 70 and 150. If your too low you need juice right away. Next comes a shot of insulin, then breakfast. For breakfast you need 45 grams of carbohydrates.
Carbohydrates are what diabetics measure in their food and meals in a day.
You never know what your blood sugar will be because they need to balance meals, exercise, sports and the amount of insulin you get every day. Snack time is at 10 and 3 and is about 25 grams. Lunch and dinner is 45 grams but before dinner you need a finger prick to test your blood sugar and a shot of insulin. It seems like she gets extra special attention from my parents. I think that they buy her material things because they feel bad for her that she gets finger pricks and shots for the rest of her life.
