WTF does 'have allowed your son's medical condition to become a power struggle' mean? It sure sounds like Abby is blaming the mom for grandmother's irresponsible and undermining actions.

I mean, I think the suggestion of arranging a meeting between grandmother and doctor is the a good one, because maybe the grandmother is one of those people who will only listen to an authority, because god forbid she actually treats her daughter like an adult who must be taken seriously.

But I'd be banning her now, not waiting. She can't be trusted now, and this could really hurt the kid. It's certainly not helping him understand how his diabetes should be managed.

I'd also be looking for someone else to be the kid's back-up emergency adult instead of grandma. Especially in medical emergencies...
