I have two tamas Boy & Girl just turned to toddlers 2 hours ago and how do u get them to be nonuniversal teens like young kutchi patchi or ichigotchi
Giving good care means trying your best to keep the Happy and Hungry hearts as full as possible - all the time.
If you let the hearts empty out, your tama will get sick and will die if you don't fill them.
You won't even have a Universal tama just an egg with wings and a halo...
Sometimes tama babies/toddlers fall sick (it's part of the programming) and you have to cure them anyway. It might affect what character you get - but the care you give - like keeping Happy / Hungry hearts full (mentioned above) is what is the most important
