Adjustable cribs

Abstract

An adjustable crib includes a base and a bed frame which is connected to the base. A tilting device is connected to the base and able to title the head end of the bed frame so that the head of the baby can be located slight higher than the stomach. A rotating device is connected to the base and able to rotate the bed frame, such that the left side of the baby's body is higher than the right side of the body. The specific adjustment of the crib effectively prevents the baby from throwing up after having milk.
