Our daughter was diagnosed with type 1 diabetes at 12 months of age. I've been reading more about the impact of exercise on blood sugars.
Any activity can have a blood glucose lowering effect, just like planned exercise.
This can be quite difficult to assess in an active two year old, particularly as frequent testing is not always easy in a child so young. Ideally, if you could pattern her blood sugar response to a few of the most common activities, by checking before and after about a half hour of activity, you would have a sense of what the activity does to her blood sugar. You could then use this knowledge to predict her typical response, and, most importantly, prevent hypoglycemia without necessarily having to test every time. We can understand the challenge this presents. Although this will vary per individual, in general you can estimate that a half hour of moderate activity will burn off about 15-30 grams of carbohydrate with regard to effect on blood sugar.
