Hush, little baby, don't say a word,
Mama's going to buy you a mockingbird.
And if that mockingbird don't sing,
Mama's going to buy you a diamond ring.
And if that diamond ring turns brass,
Mama's going to buy you a looking glass.
And if that looking glass gets broke,
Mama's going to buy you a billy goat.
And if that billy goat won't pull,
Mama's going to buy you a cart and bull.
And if that cart and bull turn over,
Mama's going to buy you a dog named Rover.
And if that dog named Rover won't bark,
Mama's going to buy you a horse and cart.
And if that horse and cart fall down,
You'll still be the sweetest little baby in town.

You don’t need as much sleep now as you did when you were a little baby. But how much sleep do you need and what happens when you don’t get enough sleep?
Sleep is a behavioral state that is a natural part of every individual’s life. In addition to learning about the importance of sleep to health, an NIH curriculum supplement on sleep, sleep disorders, and biological rhythms for grades 9 to 12 uses sleep as a way to understand scientific concepts and the purpose of scientific research.
