It's Christmas Eve but disaster has struck at the North Pole. Rudolph the red-nosed reindeer is sick in bed and Santa is one reindeer short. Rudolph suggests that his little sister Ruby go in his place. Neither Santa nor the other reindeer are keen on this plan because Ruby is extremely excitable and flighty, but they don't have much choice. Ruby makes a mess of things and causes Santa to miss out one of the houses on his rounds, leaving Ruby behind as well. When Mrs Claus goes back to correct her husband's mistake she finds that the children have woken up to find Ruby in place of their presents. Fortunately, everybody seems happy with this arrangement.
It's a little bit early still, but if you're starting to get ready and looking for books to read your kids in the lead up to Christmas, this picture book written by Nicki Greenberg is not a bad choice. The simple illustrations, including an overexcited reindeer stuffing her face with Christmas pudding then drinking out of the toilet, are appealling to little ones (as tested by my preschooler and toddler). The text is modelled on the classic Clement Clarke Moore poem Twas the night before Christmas, making it great for reading aloud.
The Naughtiest Reindeer is a fun, whimsical little story and I recommend it for ages three and up.
