Deck the Halls.
Make a family day of it. We went out for Chinese Food after Church, hit Walmart for the tree, had a hop on Santa's lap (bye bye memory of Mall Santa - Santa's at Walmart now and gives you a free photo in an hour). It's always exciting to see what we've collected and decide where to put it. Playing Christmas Carols in the background.
Hint #1 - There's nothing Joyful or Merry about hissing "don't touch!" Put the breakable decorations up high and keep plenty of plush Santas and Frostie, wooden Manger Scenes, fabric decorations, cheap
Nutcrackers and Santa Hats down low - meant for playing.
Hint #2 - Hit the Thrift Stores and Garage Sales. You'll find all sorts of ornaments and decorations that bring back warm and fuzzy feelings for you.
My mom handed down some ornaments and I realized how much I'm carrying on my childhood family traditions. I was especially happy to hang the 30 year old plastic mistletoe on the entry chandelier.
Dude, plastic lighted Santa was only $20 at Walmart. I could not resist the simple pleasure.
