Ding Dong Bell is a traditional nursery rhyme that was published first time in 1580 (!) This means that the nursery rhyme Ding Dong Bell is soon to be 450 years old! How crazy isn't that? Try to explain this to the kids. It can be hard, because it is difficult for them to imagine (maybe for the parents as well...)
Be aware that the Ding Dong Bell lyrics can be a little scary to many children ("...to drown a pussy cat"). Explain to the kids that they NEVER must do such things to animals in real life. They should treat animals with love - the same way they treat their friends.
