My mother, who has authored and illustrated some 30 children's books, was often criticized by her editors for using multi-syllable words in her stories, even when the main characters were dinosaurs! The editors believe that children should only have to deal with simple words, and they even had a suggested maximum set of such words. The editors didn't win that argument with mother, and I certainly have observed that generations of children love reciting multi-syllable dinosaur names and other tongue-twisters. And it may also have kept the caregivers who read the books from growing bored.
