Dear classmates :
Here is some history background of children's songs
We found that children from two to eight will especially enjoy the farm, what with the trampolines, slides and other play equipment. There is a whole farm of animals to see: rabbits, lambs, calves, birds of prey and ponies.
we can't find any written records of children's songs until the 17th century.
From then on, we could find some written records of children's songs , such as,
Three blind Mice , Tales of Mother Goose, Little Bo Peep and Lodon Bridge is falling down. All these famous children's songs we still teach our students to sing.

In 19th century, Sir Walter Scott and the Brothers Grimm, the great collector started to collect and published the traditional children's songs and fairy tales.
Halliwell published "Nursery Rhymes of England" in 1842 and "Popular Rhymes and Tales" in 1849. They are probably the two greatest collections of children's songs.
From then on, people are interested in and started to study the collection of children's songs.
Please enjoy !
