Our T1D kid has been pumping since 18 months. He was diagnosed at 12 months old. He's six now and has been pumping nearly the entire time.

We're in Vietnam but we do all his endo related medical stuff in Singapore.

Counting carbs in kids is a nearly pointless endeavor. Picky eating habits, nutrition mis-labeling (good luck finding accurate nutrition information in Vietnam), etc. And you'll also need to consider that their bodies are moving targets with hormones, growth spurts, etc. It's going to be really hard to manage just by math alone.

Being five years into it now, because the math seems to be changing daily, we are doing it almost by feeling backed by CGM evidence. In our case, the only CGM available here is the Freestyle Libre which is mildly inaccurate except for informing us on the general direction his blood sugar is taking. It's enough info that we've gotten his hb1ac into near normal range and the miaomiao3 turns into a full fledged CGM that we can use with nightscout and xdrip4ios for realtime monitoring.

I'd also advise you to think about joining a group of parents of T1Ds because there's a lot of things to learn and I've personally found it helpful when working through edge case scenarios that will eventually happen.
