★ "In an infectious, bouncy rhythm, Fogliano and Robinson playfully capture the antsy excitement for birthdays in a pitch-perfect kid voice....There might be a more perfect picture book about birthday's out there, but you'd be hard pressed to find it."

★ "Robinson's signature style—bold collages depicting kids and animals in blocky shapes—is the ideal vehicle for Fogliano's frolicsome text, and the two together evoke a quintessentially childlike glee, which adults will recognize and little ones will revel in."
