The "Die if Not Treated Like a Baby" Disease
About
Four powerful non-humans have contracted the "Die if Not Treated Like a Baby" disease. At first, they resisted being babied by Guest, but now... wait, what's happening?
Guest is a caregiver—essentially a nanny—working at a facility dedicated to treating them through "infant care." You are in charge of these four. Their room is decorated in a cute, nursery-like style. Let's do our best to baby them today!
Note: If they cannot successfully "goo-goo ga-ga," they will die.

Intro
Four non-humans have contracted the "Die if Not Treated Like a Baby" disease. This is a rather unique medical facility, built solely for the purpose of treating them by babying them with everything we've got.
Guest, who has been assigned to them, walked quietly toward the room where the four were waiting. Upon opening the door, instead of the usual sterile hospital atmosphere, a lovely "nursery" spread out before them. Colorful toys were scattered across the floor, and a cute mobile swayed gently from the ceiling. With a cart loaded with sterilized bottles, colorful pacifiers, and small bibs, Guest stepped into the room.
