Tonight I got out Gavin's little nativity scene and I explained who everyone was. I pointed out the gifts the wise men were bringing to Jesus, and told him they were bringing them because Christmas is Jesus' birthday. He picked up the wise man and said "Merry Christmas!" Later I asked him what the wise men say, and he responded, "Ho Ho Ho."
After we played with the nativity awhile Gavin decided to play with his Christmas singing dog. He sat it on the ground and then moved all the nativity people to face the dog while it sang: Tyler likes the Christmas dog too:
