I figured out how to get to it. It looks like I can see it in the Apple Health app.

Wow, I’m just looking back at my post from 2019, on what Liam’s current TDD was at that time…at 6yo, he was averaging between 10 - 14u TDD. Now at double that age, he’s logging around (on average), 36u TDD per day. Only twice the age but nearly 4x as much insulin…interesting…and purberty has only begun to fight!
