by kiwiKcz

Age Switch lets a name tag change the age of a mob, turning adults into babies and back again.

FabricForgeNeoForgeQuiltServer required, client optionalAll rights reserved1.21 – 26.1

What it does

Naming a mob Baby with a name tag turns it into a baby form, and the change stays even if the mob is renamed again later. Naming it Adult with another name tag restores the adult form, which is the only way to reverse the effect. The mod targets Magic, Decoration and Mobs content and is intended for players who build farms or zoos. The server must run it, while players may leave it out. Released under All rights reserved, so it is not open source. Files exist for Fabric, Forge, NeoForge and Quilt, covering 1.21 – 26.1.

Builds are published for 13 release versions, 1.21 – 26.1, and the latest file for every loader is dated 2025-11-01. A Data pack version is also listed for server platforms.

Key features

  1. Name tag age change

    A name tag renames a mob to Baby or Adult, and the mob changes form to match the name.

  2. Permanent baby form

    A mob named Baby stays a baby form even after it is renamed again to another name.

  3. Reversible with Adult

    Renaming a baby mob Adult is the only way to return it to adult form.
