Babies animals do not sapwn naturally in Minecraft 1.20.1 with any version of Forge

[Vinz]

In all the forge modpacks that I have created and played for version 1.20.1 of Minecraft, the baby animals do not spawn naturally, and in previous and later versions they do spawn, this bug is independent of the version of forge, but it always affects minecraft 1.20.1.
This only affects animal mobs, other mobs such as villagers and zombies are not affected by this bug, and mods related to animal mobs such as Alex's Mobs also affect the spawn of their mobs. I know it's a minimal error, but it takes away a lot of the immersiveness that Minecraft was already providing,

I would like to know if there is or will be a solution to this.

Does it work when you DON'T play a modpack? Just use the stand alone launcher?

I already tried it, and it doesn't work.

I am realizing that probably the mobs that should spawn as babies do so in their adult form, since some animal mobs such as polar bears spawn in pairs at the same coordinate, as a baby would do with an adult mob.
