Christmas is such an exciting holiday for my children. Me personally, I explain to my children the purpose of Christmas while allowing them to celebrate by giving and receiving gifts. If they receive a gift earlier than Christmas day, depending on where it's from I allow them to open it if they want. The gifts that are at home underneath our tree are not allowed to be opened until Christmas Eve. Well they are allowed to open 1 gift that Eve and on Christmas morning they are allowed to open the rest.
