Toggle Baby Mobs
by aaddrick
Toggle Baby Mobs lets players switch many mobs between baby and adult forms using a craftable Age Potion, right-clicking the mob that should change.
What it does
A player crafts an Age Potion and right-clicks a mob with it to switch that mob between its baby and adult form. The recipe yields four potions per craft. The effect covers villagers, zombies, cows and many other entities, including farm animals such as cows, pigs and chickens, hostile mobs such as zombies and piglins, villagers, wandering traders, and wolves, cats and other pets. Ghast Tears are part of the potion recipe.
The mod is aimed at players who want to breed animals, keep a pen of young livestock, or change how hostile and trading mobs look on their world. It works in singleplayer and on multiplayer servers, so the server and every player need it installed. The toggle reads the vanilla IsBaby NBT tag, which lets it work across a broad set of ageable entities. Translations exist for 10 languages, including Japanese.
Toggle Baby Mobs is built for Fabric only, with a single release, 21.4.0, for 1.21.4, published on 2025-01-29. The code is not open source; a custom license applies, and public links cover the source code. Bug reports and translation work are taken through the project's GitHub repository.

How it compares
Baby Zombie Removal is the server-side only, open source option for the 1.21.8 release, under the MIT License, so players join without installing it. Toggle Baby Mobs requires both the server and every player, and its single file targets 1.21.4 only. Wandering Trader Command is a client and server open source mod under the MIT License for 1.21 – 1.21.4, covering trader commands rather than age changes.
