What were some particularly interesting nursery rhymes when you were a child?

One of the most interesting nursery rhymes in childhood should be childhood. I still remember him, because the heroine in a recent TV series is called childhood, so every time I hear this name, I always think of this song that my mother used to sing to me when I was a child. At that time, I always had to listen to this song to fall asleep, otherwise I couldn't sleep.
