Taz,
We are trained in this country to hide, conceal, and lie about incontinence. It is a source of shame and embarrassment for anyone forced to live with it. If it were me, I'd hide in denial as long as possible. Wouldn't you?? Step one is definitely a physician. Almost 70% of the time, in women under the age of 55, incontinence can be reversed. Yes. R-E-V-E-R-S-E-D
So...
A.) Go see if it can be reversed.
2.) Get her some Abena Abri-Flex protective underwear for the time being.
