I have also found some books that are a collection of poems that are either already in my library or on my wishlist.
Here are the links to the books.
A Pizza the Size of the Sun
Color Me a Rhyme- Nature Poems for Young People
The Complete Tales and Poems of Winnie-the-Pooh
Where the Sidewalk Ends
What fun books of poetry have you found for children? I would love more book recommendations.
