Every night, as I put my two-year-old son to sleep, I recount his day to him, and I end with "And that was Kai's day on $MONTH $DATE, 2025." Every night, he yells "NO! NO TWENTY FIVE!" and I tell him that's just the year, it's not my fault, and I can't change it. I don't know where it comes from, I don't know why he does it, but it's very consistent.

Last night, I finally told him "And that was Kai's day on January 1, 2026." His eyes lit up, and he shouted happily "Twenty six!!!"

I don't know why he was fighting that particular battle, but he has won it at last.
