Megan has been asking me about everyday when Christmas is. The solution was to make a countdown chain.
Each night at bedtime Megan cuts off the lowest link. When Christmas arrives all that will be left is the star at the top.
Luke 2:11 is written on the star. After we read The Story of Christmas by Patricia A. Pingry we then read the scripture. This is working so well that I plan to make it an annual tradition.
