Some of our favorite holiday traditions growing up were the annual ones - like decorating the Christmas tree and setting up Easter eggs hunts.
There's one tradition we started a few years back that's become firm favorites for everyone involved: each Easter, we do an Easter egg scavenger hunt where kids have to solve a series of riddles or clues to find their treats - it's fun watching the kids work together and figure them out.
We also love planning summer picnics and usually make a day of it. Everyone has to prepare one unusual food item to bring along; it's become quite competitive through the years, but it's so much fun!
Another tradition we have during colder months is "Fort Night". We turn off all screens and build forts using blankets, chairs, and whatever else we can find. We tell stories, play board games, and often end up watching old family videos - the kids love seeing themselves as babies. It's nice to have that disconnect from everyday life and focus on each other.
