It seemed you needed an interpreter to figure out what the author was trying to say. It used to be that adult poetry was given to children. But that makes no sense. Times have now changed and materials are much more readily available that children can enjoy. Poetry is more meaningful to them.
Poetry can capture the things that children experience.
Poetry for young readers is usually short and accessible in structure. Children s collections are good because there s silly poetry poetry that invites young children to just enjoy the sounds of the words, that creates images that they enjoy saying. You look at kids when they hear Mother Goose. It s nonsense but they want you to read it again and again. Also, educational methods have changed.
