As I've answered you before, I continue to think this child is probably going to be diagnosed with Type 1.

However, as you've researched, it can take a while.

In the meantime you should know that illness caused by high blood sugar begins at about 240.

Unless you get in a study of an experimental drug, this is going to take it's course no matter what you do.

The thing is, it's not high enough to treat yet. I think you're doing the right thing by keeping an eye on it. Hydrate him as much as he wants as this will help the remaining insulin do its job.

If his blood gets above 240, and your doctor still won't treat, then go to an ER. They will call in a diabetes specialist.
