for The Little Christmas Elf by Nikki Shannon Smith and Susan Mitchell
Nina, the littlest elf in Santa's workshop, doesn't finish the teddy bear she's making in time for it to get loaded onto Santa's sleigh-but, encouraged by Santa Claus himself to not give up, she works far into the night to finish it. While Santa is out delivering presents, a baby is born. Santa comes back for Nina's now-finished bear—and guess who he takes along to deliver it?
