This is a Version 0 release and will have glitches and bugs.
I do not recommend this mod for beginners. Not at this stage of development.
What this mod does
This mod attempts to give the impression of your Sim kids growing up.
This mod updates Children and Teens every night to simulate the physical process of growing up.
They grow in body height and shape and their voices are adjusted accordingly.
When the Sims turn into young adults, all the modifications are reverted as if nothing has ever happened.
Of course you can activate and deactivate the mod for each Sim. Or have the mod auto update everyone.
You also have to activate it manually for each world/savegame you are playing. So having one game with growing Sims and another with standard Sims is absolutely no problem.
How fast they grow depends on the lifespan you have set for Child and Teen in your game.
