Hi - and welcome - I wish you and you husband all the best on this journey.
The thing that gives me the most confidence in my journey is my Libre 2 - this is a Flash Glucose Nonitor (FlashGM) - it is important to note that there are plenty of other options, most of which are continuous glucose monitors(CGM) … which don’t need to be scanned - so perhaps they’re even better? I don’t know - what I do know is that the tech is there to help manage T1D so It’s definitely worth doing your research, working out what is possible, and talking to your specialist.
That said, the libre 2 (whilst in no way perfect) has (assuming you are using your phone to scan) the added advantage of allowing a loved one/ parent / guardian to be notified with your sugar level whenever you scan and, perhaps more importantly, whenever you trip an alarm. This can produce huge peace of mind. The libre ,like all these devices, also diminishes the need to finger prick! Most importantly it’s widely available on the NHS (for those that qualify) and reasonably affordable even if you have to self fund - it has provided huge peace of mind for for my wife and I. So, not an advert - just a huge fan!
That said, you and your husband need to find your own balance, your own pace and your own tools to deal with his diabetes. Best of luck!
