The smaller holidays are easy to skip until the week arrives and you want a book that matches the day. A Thanksgiving story, an Easter egg hunt, or a Valentine mix-up gives a preschooler a picture of what the house is about to do.
You do not need a different book every day of the season. Bear Says Thanks and A Turkey for Thanksgiving cover a November meal from two directions: friends bringing food, and a turkey who would rather not be the food. In November is the quiet one, for a walk or a window.
The Easter Egg is a longer look at the pictures. Pete the Cat: Valentine\'s Day Is Cool is the short, funny one for a classroom party week. Read it once for the story and once so they can spot the valentines.
Put the holiday book with your regular bedtime book. The holiday one explains the day. The familiar one gets them to sleep.
Read it the day before the holiday, not during the meal. By the time the table is full, they already know the story.
