One of our family's Christmas traditions is to have a birthday cake for Jesus at Christmas dinner. This is one of my favorite traditions because it's something tangible the little ones can understand.
Birthday Cake = Birthday
Christmas = Jesus' Birthday
Last year at just 4 months Gabe was way too little to even taste the cake and even four months ago at his first birthday Gabe had no interest in cake. But Gabe decided birthday cake was a good thing this time and he really enjoyed muching on Jesus' birthday cake.
