Is the Three Billy Goats Gruff a story for little children?

Yes, it can be considered a bit intense for some, like hansel and gretel, but it is a traditional children's story.

Answer:

Many "Children's Stories" are instructions for life. They are meant to be told to children to help them to avoid serious problems but are wrapped up in entertainment. The Boy who Cried Wolf is about telling the truth or at least improving on lies every time you tell one (never tell the same lie twice). Hansel and Gretel tells children not to disobey their parents, not to leave home for unknown areas, not to trust strangers. Little Red Riding Hood is a story about following instructions exactly and not being trapped alone with sexual predators. The Billy Goats Gruff is a story of strategy worthy of Sun Tzu- specifically, avoiding confrontation with superior forces until your backup arrives.
