Christmas is coming, and we hope to teach our tot about the season. Simple things like Santa, presents, gifting others, Christmas tree. How should we start?

Christmas is actually a cultural and religious celebration of the birth of Jesus Christ. https://en.wikipedia.org/wiki/Christmas Santa, presents, gifting others and the Christmas tree are actually part of the commercialism of Christmas. If so, you could teach your child about St Nicholas who gave gifts to others, and maybe give him a budget to purchase presents to give to other children in need. http://www.livescience.com/42089-kid-s-belief-in-santa-is-healthy.html
