Not to throw a wrench in here because I’m 100% on board with you.....
But I have a 12 year old type 1 diabetic child. He wears a Bluetooth device on his body to monitor his glucose levels. Now the machine itself uses a monitor which would be honestly fine for an adult. But he is a kid, doesn’t make the best choices all the time and hormones as he is aging affect his glucose.
If he has a cell phone, the app used can transmit his levels to us and notify us he goes too low or too high. It also tracks his meals and insulin that he takes.
Point is, it allows him to be more of a kid and gives him freedom he wouldn’t normally have, like staying at a friends house with parents that aren’t t trained With diabetic kids.
THAT....is the one reason he has a cell phone. Which we monitor and limit what he can do on it.
