For the past month or two, Liam’s TDD has gone up from between 5 - 7 to between 10 - 14 TDD. I’m also noticing that, coincidentally perhaps?, we are not getting as long of a lifespan from each of his sensors. Now, logi…

Liam has the flu (so does three of his brothers). Today, his TDD is 20 units and the day isn’t even over yet. Oh, and he’s still been high, over 200, still about 70% of the day today. Crazy his illness wrecks the syst…

Right now, Liam takes so little insulin (TDD between 6 - 8 units). Just reading @docslotnick's response on how much basal he uses per day got me wondering. How much TDD should we anticipate Liam using when he enters pu…
