Hello! I'm not a medical professional, just the parent of a kid with diabetes. The normal blood glucose ranges for anyone, child or not are between 80 and 120. Some doctors will say 70-110, but it's all in the same range. Now, that's the target, but depending on what is eaten for example, a healthy person's blood glucose can rise temporarily up close to 200. As long as the values return to normal after a couple hours, all is well.
