Hi Nikki,
I know how frustrating this can be...my "little sis" (she's in her early 20s!) is also T1...she's very closed to me so I have little idea of much of what goes on in her life (we don't live locally to each other) but when we are around each other, it can seem like she hardly ever tests, doesn't carb count etc...she tells dad she has good control & good results, but I'm always worrying that the only reason she thinks this is cos she only tests if she feels a bit low (ie "I hardly get any high BG readings") and hasn't done any structured diabetes education like DAFNE so doesn't really know what the ideal levels & best ways to control things are. She bitterly resents anything she feels is my intrusion / interference / nagging / being a horrible big knowitall sister, so over time I have just had to learn to wind my neck in & let her live her own life (anything I say just makes matters worse!). I know this is totally different from an OH situation, but this ramble was just to say I can appreciate both sides of the wire!
🙄 Not knowing your OH, I don't know what to suggest really - maybe gentle encouragement to do something like a DAFNE course (Dose Adjustment For Normal Eating) might help, or it might just wind him up...sorry, that's not much help I know! I guess just try & remember controlling diabetes for most people is not easy, and can be extremely frustrating, so just be wary of adding pressure... (I'm sure you don't, just stating the obvious
😱!)
(Off the subject, & back onto 1st Aid courses - totally, yes, EVERYONE should do one! Guess the courses I have done have just had the dodgy lecturers re diabetes! First course done for cadets when 15, thankfully not needed to apply first aid much since, although there was one notable time when a guide dog led his boss into the path of a van at a crossing! D'oh... SO not funny at the time, but I did have to smile wryly at the look of abject embarrassment on the labrador's face...! Is there any breed that can look more embarrassed than a labrador in the wrong?!
