My DH was doubly incontinent for the year before he died, and because I was nursing him at home, with help from visiting carers twice a day, it sometimes fell to me to, " do the necessary."
Believe me, I was not at all confident of the strength of my stomach. But I needed to do all I could to keep my dear man out of a nursing home. The carers taught me a few tricks of the trade.
It gets a bit graphic now, so please go to the next post if squeamish.
Your DGS will probably use pull-up pants, and the trick is to rip/cut the pants down both sides, and roll the pants up, thus containing the contents.
Synonymous's comments about being well prepared were spot on.
Have everything to hand, including disposable small , square , waterproof sheets, sold in most chemists. A spray-on hand sanitizer is also essential., even if you are using latex gloves.
I also kept a bowl of water, sitting on the window-sill, with essential lavender oil in it.
If everything you need is at hand, the changes can be over at lightning speed!
Do try to go for it Supergran. Really earn your username, and be proud of your fortitude. Your family will be so proud of you too.
Be strong, and be there! Good luck.
