Santa Mouse. Something about this simple story and sweet illustrations stuck in my head from childhood. I remember reading this book again and again. When my turn came to be the mom reading Christmas stories, I hunted it down. We look forward to it every year.
Olivia helps with Christmas is a classic! I absolutely love this book, from Olivia's insistence that her father not build a fire in the fireplace ("DADDY! WHAT COULD YOU BE THINKING? DO YOU WANT TO COOK SANTA?!") to her helpful decorating, which includes "finding" a little tree. Curiously, the top of their "real" tree is missing. This holiday story of the privileged, sassy pig brings joy every time we read it.
