For teens with T1D

It's your body. Time to run the show.

At some point T1D stops being a thing your parents manage and starts being yours: parties, sports, driving, sleepovers where nobody's checking on you. That shift is a skill, not a birthday. It can be learned in pieces.

No lectures here. Just practical stuff: handling glucose around sports, what to tell friends (and what you don't owe anyone), and taking over your own care one step at a time.

Sleep, recovery and the next day's insulin
