Using stickers is a fun way to help your child count down the days until Christmas. Your child will enjoy being able to place a sticker on the right ornament each day.
I just buy the sticker books in the school/craft section of Walmart, and they fit the circles nicely. Or you could let your child cut out some construction paper ornaments to place over the numbers, or even just color in the circles with a crayon.
