"Na’s wonderfully illustrated debut is one of those bedtime books that children will likely turn to again and again."
Review, New York Times Book Review, December 6, 2009:
“So thoroughly does the book inhabit its sleepy world.”
Starred Review, Publishers Weekly, September 14, 2009:
"It's the rare picture book that, upon arrival, feels as though it has been around for years already"
Starred Review, School Library Journal, November 2009:
"Nimble lines influence the gentle mood through spotted colors and shaded images, balancing darkness and light to depict the passing of time."
