my son is 8, was diagnosed a year and a quarter ago and has been on the pump for about 6months. We've gotten most of his numbers sorted out, but still struggle in the evenings and night. We found he would go low an hour or two after dinner (say dinner at 6:30 and low at 8:30), then very high around 10:30 or 11:30. We ended up having some crazy pump setting with a very high carb ratio (over 40) and also very high basals (about twice what he has during the day), which makes no sense to me, since if he's less insulin resistant at night he should need lower basals, right? Anyway, my new theory is that the carbs just get into him slower from dinner time on, and that we need to dual wave him for every dinner and dessert/snack. Has anyone else experienced this? That carbs are a lot slower getting into the bloodstream in the evening and night?
