Baby Potion adds a new "Potion of Infantilism" brewed with the Golden Dandelion and an Awkward Potion. The potion temporarily reverts mobs to their baby form (or scales them down if no baby form exists). This mod requires both server and client to install the mod.

Custom Babies' Scaling game rule is used to control whether or not to include mobs that don't natively have a baby form. Also can be set to Chibi mode where it tweaks the models to try and match the style of the native babies.
