“[Offill’s] channeling of sibling snark is a thing of beauty. Blitt mischievously and masterfully choreographs the neverending festivities […] His watercolors will reward close-reading visual joke connoisseurs.” — Publishers Weekly starred review
“The brazen over-the-topness leavens the taunting with pure ridiculousness, but there’s still enough bite to make this absolutely hilarious, especially to older sibs.” — The Bulletin of the Center for Children’s Books starred review
“Offill must’ve had some sibling rivalry as a child, because she knows just how to dole out exquisite torture with an insidious, offhand tone. Blitt makes for the perfect coconspirator, contrasting the kids’ almost-maniacal partying with the napping child’s big-headed, about-to-blubber innocence. Simply brutal! And quite funny.” – Booklist
