Hush a bye baby
Hush a bye baby, on the tree top,
When the wind blows, the cradle will rock;
When the bough breaks, the cradle will fall,
Down will come baby, cradle and all.
Nursery rhyme origin
This very popular rhyme probably originates from the days when women working in the hop fields, would tie their babies cradles to the branches of trees to allow the wind to rock them to sleep.
Another possibility is that a Pilgrim youth, a passenger on the Mayflower, wrote the rhyme after seeing the way Native American women rocked their babies in birchbark cradles.
