My preschooler and I enjoy reading this book together.While the rhymes could be a little better they aren't too bad. The writing is good enough that it keeps both a child's and an adult's attention, which can really be hit and miss in children's books. It's an interesting behind the scenes look at a zoo and the work zookeepers do to care for the animals. I like how adaptable it is too for different age levels. My preschooler at this point simply enjoys the main rhyming text. There's also a sidebar with much more information in a smaller font. I'm sure we'll be adding in reading the sidebar in a couple years. The illustrations are rather pretty as well. Overall, I'm glad I own this book.
