It never happened.
I was going to try again this year. We ran out of time on Christmas Eve. On Christmas we realized we were out of eggs. In the end I decided we would have cake on the Epiphany instead. We told Caitlin that Christmas was his birthday, but that this was his birthday party.
I also gave up on the cake and let her decorate it herself. It was more fun that way.
It might just have become an accidental tradition.
This is video of Sean blowing out the candle. It took a while, but he got it in the end.
(And no, he was not as close to the flame as he looks there - it is the camera angle!)
We also painted the ornaments we’d made earlier. (Another Christmas project we didn’t get to until after the fact!
They had a blast with our final Christmas fun!
