HOW DO I MAKE MY KIDS GROW FASTER? Edit
Go to the main screen of Minecraft (once opened), select "MODS". Scroll down to the MCA mod, click "MODIFY" (or any synonyms of this word), and select the amount of time you'd like for your babies to grow.
If you want (your kids only though) to grow give them a golden apple(normal not enchanted).
