You are right, I had misremembered it! Thanks for fact-checking :)

Type 1 here - pretty much. They did some tests on identical twins and found that in almost all cases, once the first twin develops T1, the second follows within a few months (edit: I had misremembered this)

2 years might not make much of a difference to folks like me who developed it as adults (I was 30), but it’s significant for young children.

Having T1 significantly impact your routine, and it’s pretty difficult to manage especially for very young kids (think: toddlers) who can’t truly understand what’s going on, and very much struggle with diabetes management - and parents too! Also, even two years could lessen the long term risks associated with T1 (think: retinopathy, kidney disease, diabetic foot, etc.)
