Every family tradition started somewhere, which means there's always room to add a new one. If your holidays feel like they need a refresh, consider starting a tradition around giving rather than just receiving, like picking out and donating a toy together each December.
A yearly ornament tradition is an easy one to start: choose or make one personalized ornament each year, and by the time your kids are grown, they'll have a tree's worth of memories to take with them. Similarly, a first snow hot chocolate ritual or an annual pajama-decorating night costs little but becomes something kids look forward to year after year.
The best new traditions are simple enough to repeat without stress, since consistency, not extravagance, is what actually makes them feel special over time.
