mamabunny and Pea-n-Me, thanks so much for the great suggestions!
Maybe we'll just starve her during the trip.....JUST KIDDING! I have to keep a sense of humor here because the thought of an accident really stresses me out!
I'm going to tell you my worst "accident" story, and it's a doozy.
As I said before, my Mom had stroke-related dementia. She was "locked in" for the last year of her life, and during that time she started having "catastrophic reactions" to ordinary everyday events. Catastrophic Reactions tend to be rapid onset, and can last for any amount of time, and be for any reason. In Mom's case, she actually became afraid to toilet, and many of the CR events that we had with her were related to toileting. Minimally, she would become extremely emotional.
The maximum was hit the night that she became afraid to poop, and when she could finally hold it no longer - and we got her to the toilet in time - she became afraid of the poop coming out of her. Before I could stop her, there were handfuls *everywhere*.
The cleanup took hours of scrubbing, disinfecting, mopping and laundry, including showers for both of us. To this day, I'm not sure who was more traumatized in that moment - her or me.
I encourage you to talk to your Mom openly about your concerns. Let her know you are worried about this, and that you have real concerns about this happening at Disney World. Explain what you see as the worse case scenario, and how you think it could play out. Maybe she hasn't really considered what would happen. A lot of newly diagnosed people engage in "magical thinking", and none of us are exempt from that.
I understand your stress - especially when we are caregivers for our Moms, it's difficult. You never want to think that you will have to be the one who cleans up after a bathroom accident - it's a step too far in the inevitable role reversal we have as adult children. Just know that it *can* be a *lot* worse - and that as long as you and your Mom can keep your sense of humor about it, you will get through it just fine.
And remember that if you need a really big cleanup on Aisle #2 that the First Aid center in every Park might be a good place to head to.
Good Luck
