It's true, the Powerpuff girls were not voiced by child actors but by adult women. Most child characters in cartoon series are voiced by adult women because traditionally, most cartoon characters don't age or only age a little, and most women have high pitched voices so they can do the character for years when a real kid's voice would have very likely changed. Just look at Nancy Cartwright, who voices Bart Simpson. The teacher is a real know nothing know it all.
