Kai was 7 when he went on the pump and will be 14 on Saturday. It is the best thing we ever did for him, diabetes related, but carb counting is key. It makes life much more flexible and manageable, especially when they are small and they get the childhood illnesses and stomach bugs. My biggy was always tummy bugs that little ones get. We alway have our main meal of the day in the evening and Kai would come home from school, seem absolutely fine then a couple of hours later start with it, and then you end up in the situation where you have this vomiting 5-year-old who feels understandably awful but can't understand why mummy and daddy are forcing him to eat sugar off a spoon because he's had this huge bolus of insulin inside him that now wants to send him hypo becaues its go no food to work on. With the pump, because it works without background insulin, you just reduce the basal rate, or take it off. Same for exercise. some people say they find as a T1 difficult to lose weight re increased exercise becaues they end up taking more snacks. with the pump you can simply reduce the rate.
