Hello Jen,
That most have been an awful time for you both, I don't think I have ever seen or heard of anyone having such a high reading on diagnosis as Khaleb had. Certainly the insulins, meds and testing equipment are far advanced than they were 30-40 years ago, but the basic principles are much the same, that being the tighter the control, the better for long-term health and longevity.
Equipment aside, I think the greatest developments in diabetes is the knowledge and understanding of the condition. The diabetes consultants/nurses are more specialised and pro-active than ever before, there are better courses available for both type 1 and 2's, and the wealth of information available to hand from sources such as the Internet, all help patients adapt and come to terms with this life-long condition. I know much can still be improved, money as ever is the stumbling block in future research and developments, but in time things will progress and I sure one day we will eventually be rid of this condition altogether.
Hope you are both keeping well!
Nigel
