Our family tradition is pretty simple. My 12 yo spends the night with my ILs, has every year since he was an infant (except last year, when I had covid and we didn't want to risk spreading it). This is the first year without my FIL, who passed about 2 months ago now, so it was extra important to MIL that they uphold the tradition. Husband and I will stay at home, watch the ball drop on YouTube, and be in bed by 12:05. Welcome to your 40s, I guess.
