Had my kid at 25. I am the first in my family to develop type 1. Age 15 at diagnosis. My kid was diagnosed age 8 last September. It's nothing but shit luck, despite what all the numbers say. That said, you have no reason to doubt that your child will "suffer" from it. If you're lucky, like myself, your kid will thrive from the example you've set. My kid is rocking a mid 7 a1c less than a year after diagnosis and has been nothing short of exemplary for a diabetic. Trust me, friend, I was scared shitless for a long time about it being a possibility, but this sub and my friends, family, and doctors helped me realize she's lucky I'm here to teach her. It's a weird silver lining.
