I think about scenarios like that all the time! With my adult awareness, i would cherish and enjoy every diaper change and cleaning and all the love i'd get during those precious times. I would definitely play it up and cry everytime i was brought close to the potty and make it an almost heartwerenching ordeal to try to make me grow up. I wouldn't wanna outright tell my mom that id rather stay a baby, but i'd make it very clear that thats the only right thing for me, so my babying would come naturally ♥️. I'd love for my mom to keep babying me well into adulthood with all the cutsey things that'd come with that.
Thinking about stuff like that is one of my fav pastimes, its too cute.
