My aunt is defiant against me and I've always been so good to her, but now won't do anything she is told and wets her bed everyday due to not wanting a diaper on. She won't let me touch her to help her. If I do she yells like I'm hurting her when I'm only touching her. I'm at a loss don't know what to do?
Hugs for all you do, this is my personal deal breaker so my heart really goes out to you. I hope you find something soon.
No diet or supplements should be instituted without the approval of the doctor, there could be drug interactions, diet restrictions or other factors that need to be considered.
Just my opinion
For me, I never round a magical solution. I just kept at it until we are as good as where we are right now. It took grandma years to get here. Washable diapers may help. They are much more like regular underwear and thus they are more likely to keep them on. Also, make sure you get the right size. It seems that even the small sizes in the US are made for obese people. They are for people up to 40" in waist. That's far too big. If they are too big and thus uncomfortable, then they will be more likely to take them off. I found a brand that sells XS sizes which fit much better. My mom went from taking them off all the time with smalls to only rarely now with extra small. She always complained about how big and baggy the smalls are.
In in interim, you should look into waterproofing the bed. Check the incontinence forum for tips on that.
