Well.....I guess you could say we limit carbs. When Ds was first dxed, we sat down with the dietician and she asked about Ds's eating habits, then made him out a meal plan showing us how many carbs he would get each meal. Right now, Ds's meal plan allows for 60 carbs for breakfast, lunch, and supper, and three 15 carb snacks daily. Now, he also has an insulin to carb ratio for when he eat more or less carbs. Pizza, birthday parties, etc. always mean he will be eating more carbs, but for the most part, we try to stick with the meal plan on normal days. We find he runs better numbers when we stick to the meal plan. The doctor said it would also help keep his weight stabilized in the long run. I would have been concerned that your Dd would have gotten low without eating her grapes. Were they included when you carbed for her insulin?
