Despite Candlewick Press, Amazon, and Barnes and Noble stating that Who Is Sleeping? won't be released until February 2019, the book is available from Candlewick and Amazon.

Another Petr Horáček board book with bright, dynamic illustrations, Who is Sleeping? is a lift-the-flap first concept book. "Who is sleeping in the tree? Who is sleeping under the leaf? Who is sleeping in the river?...."

I also included When the Moon Smiled which is a counting book. When the moon looks down on the farm and notices that none of the animals are asleep, the moon gradually "lights up the stars" for the animals. For the desired age group, 1-2, I think the book has more text than needed, but depending on the child, this may not be a concern.
