While younger children may enjoy the humor and illustrations, the books can be challenging for readers below this age range due to:
* Length and vocabulary: Some books are longer, with a higher reading level.
* Complex plotlines: The stories often have multiple characters and twists.
* Subtle humor: Some jokes and puns may be lost on younger children.
However, it's important to remember that every child is different. Some may be ready for Captain Underpants at a younger age, while others may not be ready until they are older. It's always a good idea to preview the books and consider your child's individual reading level and interests before making a decision.
