Even with how helpless it felt to be such a little baby, something in you felt comforted when you were like that and you wanted to feel that for as long as you could.
With your mom and dad busy elsewhere, you decide to make a long list of rules:
People now stop aging around 20
Breast milk and baby food are the only foods people can consume; anything else will upset their stomachs
People now live, at minimum, at least 1000 years
Development milestones have now increased greatly: crawling is possibly only starting at 100 years, babbling at 150 years, waddling at 200 years, walking at 300 years, talking at 500 years
Education is now impossible for humans; they will have the capabilities of 3-to-4 years olds at most
Artificial humans now serve as mothers
Humans find being infantile incredibly addicting and have greater difficulty reaching further stages of development, but living increasingly longer lifespans in exchange; those whose development never goes over 1 month old can live over 10000 years
With that, you put down your crayon and close your eyes as you feel reality change around you. When you open your eyes, you're in a giant crib, your sister and aged down parents next to you. All of you are dressed in onesies that hug tightly around your diapers. Your parents and sister act like newborns, randomly moving their limbs around and flickering their eyes across the room, occasionally having a noise erupt from their throats. Even you have a hard time paying attention to your adult thoughts, enjoying the infantile pleasure of just feeling warm and soft inside.
You then notice a woman walk into the room, her large breasts straining against her dress. "You've woken up from a long nap, my babies. Time for your milkies." The woman's soft, gentle voice makes you further relax as she lifts all of you up and sits in a rocking chair. She takes out her breasts, each of them having two nipples on them so you can take suck from her at the same time. As her sweet milk flows down your throat into your stomach and you hear the soft breaths of your family around, you close your eyes and allow yourself to become a baby once more.
