When my child was young enough that they couldn’t talk but could express themself, once I put them to bed and told them it was time to sleep. They squinted their eyes to pretend they were closed and said “honk shoo, honk shoo.”

I was flabbergasted. Turns out their mother had taught them that as a kind of meditation to progress towards sleep, but I didn’t know that and briefly thought they’d manifested it on their own.
