Chucks are a great idea AAAA. They really do help unless the person is fully incontient then we always use diapers and chuck pads. I do know i saw on a commerical that is a company that sends diapers to the home and its very disceret they might have x large sizes ill have to keep a look out for the name of the company and let you know. Is she completely incontinent or dribbles? Because if she just dribbles you can buy extra large period pads and they work just as great. They are cheaper, you do have to change them more often but you would do the same for diapers cause no one wants to sit in their own pee. If you get really desperate you could always go to your local nursing home and ask where they get theirs. They get major discounts and buy in bulk they might even offer to set something up for you like if you pay them they will order you some. Im not sure but its worth a try. I would also ask her doctor about different options. There is one thing i do want to bring your attention to though. Those who are incontient especially you need to keep an eye on how much she urinates and if her stomach ever becomes enlarged and hard. People with incontience have a greater risk of not being able to empty their bladder all the way and it can be very damaging because they arent able to control their urine output as we can. Not saying your mom has this problem but if you didnt know about that its just alittle helpful tip to keep your mom safe and comfortable. Good luck!
