Hey! See my comment here: https://lemmynsfw.com/comment/614070

Prompters need to add (21 years old:1.3) in the positive prompt and “child, childlike” in the negative prompt. They also need to judge better whether the content the AI produces is too young looking.

If you make something and think “is that too young?” Just assume it is and regenerate with the above tips. 21 is a good starting point because AI doesn’t seem to be completely accurate with ages yet.
