I have taken some traditions from my own childhood and added some. My parents used to buy/make ornaments to go along with that year. For example, the year I got my nursing license, Mom gave me a Precious Moments nurse. The year I took skating lessons, a little skater ornament. I do this with my kids and they love picking out their ornaments for the year.
We also do the Elf On A Shelf. They really get in to it. Sometimes the elf forgets to move around, though. LOL!!!
The kids get pj's for Christmas Eve, so that they have new ones for photos the next morning. We also make cookies for Santa and throw out birdseed or carrots for the reindeer. There's usually a egg dish and cinnamon rolls for Christmas morning.
The school does a Santa Shop, so that kids can bring in money to purchase gifts from local vendors and craft tables. The kids love it. However, with my oldest no longer attending the elementary school (with a couple more leaving in the next few years) we will start a shopping tradition. My kids love buying for others in the family so much. We'll be setting aside some time for them to buy for each other, as well as having a couple hours of mom/dad one-on-one time.
Here's something else that I haven't decided if I enjoy or not (LOL!!) When I was in high school, my youngest brother was still at an age where he believed in Santa. I would help my Mom put out the "Santa" gifts. Well, my oldest is 11 and no longer believes. This year, since he helped me with the "leprechauns" on St Patty's Day, he may help us with Santa. I remember very fondly, helping my mom when I was past the age of believing. However, since my son is 11 and not 16, I don't know if I'm over the fact that he no longer believes in Santa. We'll see. I have a hard time even typing the words "No longer believes".......LOL!!!!! Just a thought. It could become a great tradition in our family, since we have a toddler and many more years of Santa's helpers in our future.
I will be checking in to see what others are saying. Great question! It's never too late to start traditions!!! Thank you.
