Jonathan Stutzman and Heather Fox, the duo behind Llama Destroys the World, take their trademark hijinks up to the North Pole in this laugh-out-loud, heartfelt Christmas-themed picture book.

Santa is feeling old, and being in the business of Christmas for centuries is . . . well, it isn't all milk and cookies. In hopes of regaining some of his pep, Santa asks the spirit of Christmas to give him something for a change: skim off a couple of years and make him younger.

But Christmas magic is powerful, and Santa gets more than he wished for. Instead of a fresh new outlook and boundless energy, he needs diapers and a nap—stat. With Christmas only a few days away, the elves rush to teach Santa Baby the basics. But will there be enough time to prepare their new bundle of holiday joy for the job?

Funny and spirited, bright and inspiring, and with an unforgettable title, Santa Baby is destined to be a yuletide read families revisit every year.
