He might need the wake-up call of getting very sick before he takes a hold of things. He has to get his head around it, but I promise you, it's a hard thing for some of us to do. Some of the diabetics here find it like water off a duck's back, but I don't and I personally know others who don't either. All I can say is I wish I'd had someone to help take care of me when I was diagnosed - he should count himself lucky that he has you and your daughter because we're not all so fortunate. What you should keep telling him is to imagine how much better physically and emotionally he will feel once he's got his sugars under control (because trust me, he will, he'll feel like a different person).
