I was diagnosed at 12. I had a pump from 13-26. I'm 27 now. The pump isn't always the "answer" that everyone likes to give it. I've found Levemir to be a GREAT long acting insulin. That being said, if the pump works for you (or your child) then do that, if injections work, then do that. I hear a lot of people say things like "wow you're not a pump". A pump isn't a pancreas. The pump is only as good as the tube. Find what works for you (or your child in this case).

I will say the CGM from Dexcom is amazing. I don't wear it all the time but since starting to use a reliable CGM (the Medtronic one is terrible, Dexcom is wonderful), I've had better control simply by understanding how blood sugars react.

Insulin is like a gas gauge, you can use it that way. If sedentary you're using say 40 units then you should be hitting 40 units during intense workout times as well. The difference is during intense workout time the basal rate goes down but fast acting goes up. If you're not hitting the daily average usage then glycogen isn't full, just like a gas gauge.

Happy to speak with you further if you'd like, pop me a direct message. Whatever happens don't let any doctors tell you your son can't do anything. He can do anything.
