I've taught my son to wash his hands while singing Happy Birthday, because that's the average amount of time recommended for hand washing, and he loves to sing.

Unfortunately, it didn't occur to me that he's only 3 and doesn't really know the song very well 🙊

So he's been in the bathroom washing his hands, just repeating "Happy Birthday to me, I smell like a monkey, Happy Birthday to me, I live in a tree, Happy Birthday to meeeee" for about 20 minutes now 😂
