Childrenize

Give something or someone children features. Give someone a childlike appearance. In other words, make someone younger than they should.

ANIME CREATORS SHOULD REALLY STOP CHILDRENIZING ANIME CHARACTERS FROM THIS MOMENT FORWARD BECAUSE PEOPLE FEEL UNCOMFORTABLE WHEN THEY SEXUALIZE ANIME CHARACTERS THAT RESEMBLES THAT OF A CHILD.

Man, I don't really know why anime creators childrenize anime characters.
