Yes

THE DIAPER !, you throw off the blanket to see a sagging diaper with it's front completely piss yellow and it's back a mushy brown mess, you tried to remember what you wrote on the diaper and remembered that you wrote them on a piece of paper first to see and prove to yourself that changes did happen, you waddled back to your room in your surprisingly sturdy diaper and saw the paper you wrote by your past self with things to do with potty training and a question that you're meant to ask yourself, 'Do you know what a toilet is ?', you raised an eyebrow in confusion as you try to remember anything that has to do with the word 'toilet', not knowing that said knowledge is resting inside your undergarments as a log of turd, you read some instructions from your past self to go to the bathroom and see it for yourself, you waddled into the bathroom to see that your past self wasn't lying as you inspected the strange porcelain device and asked by your past self if you know how to properly use it, "I don't even know what this thing is supposed to be.., let alone how to use it...", you mutter to yourself and read the last text to see that if I answered no to the last 3 questions, it meant that the changes that may past self wanted have worked and calmed down as began reading the explanation that you have written for yourself to read...

"So..., a toilet is just an unmovable diaper...?, well then what's the point of diapers...?", you commented as your hand absentmindedly squished the seat of your surprisingly comfy and messy diaper as you began to think of what other things you can make other people or yourself 'excrete' into these strange diapers...
