This companion to the celebrated Mama Built a Little Nest explores the many different kinds of dens animals build for their babies.

Perhaps you’ll come across a den,
dark and deep and wide.
And it will make you wonder…
Who or what might be inside!

There are so many different kinds of dens that mother animals make for their babies, from desert burrows to snow caves to elaborate underground tunnels. Jennifer Ward introduces young readers to all sorts of animals and the cozy burrows they call home in this bouncy, rhyming picture book, illustrated by Caldecott Honoree Steve Jenkins.
