Have you tried contacting someone from your local JDRF chapter? Or maybe your Endocrinologist? I am 17 and was diagnosed 11 years ago and babysit for a few kids in my area who were referred to me by the people at our chapter. My parents are also part of a facebook group for local parents of kids with T1D so it might be worth seeing if there is one for your area, that would probably be an easy way to see if there are any babysitters familiar with T1D in your area (who would also come recommended by other parents of T1D kids so you would know you could trust them.) Hope this helps!
