Hi
@Kenbob
My wife is mainly incontinent, which I try to manage by ensuring she goes to the toilet frequently.
A lot of the time, she will "go" within a short time of sitting down however, there are times where she will sit there for absolute ages, without going at all.
I have found by trial and error, that if I stand her up, then sit her back down (sometimes several times), eventually (though not always), she will then go. It's as if the "go trigger" in her brain is missing and by repeating the activity of sitting down, it eventually kicks in?
Maybe worth a try at least?
Good luck.
Phil
