A CGM and insulin pump have made my life easier.
How old is your son?
The mental burden is SO HIGH for both the person with the condition and their caregivers. At some point if it feels right, it might be worth having him see a therapist or a counselor who specializes in chronic diseases. There's a very high correlation between depression and type 1 diabetes (last I read, you're like 300% more likely to experience severe depression as a T1D.) Especially once he goes into his teenage years, that's a really hard time for a lot of us diabetics (and sometimes during the "rebellious" phase, a kid will intentionally stop taking care of their diabetes).
> His pump beeps at him so often he's just become accustomed to it and ignores it
This is a real problem with insulin pumps and CGMs, because alarm fatigue is a real thing. It makes me mad that they insist on putting in all these alarms you can't configure, because eventually you just start ignoring it. For my CGM, I use xDrip which gives me much more customization around my alarms: I just leave on the ones that are important to me.
