A baby rattle is a rattle produced specifically for the amusement of an infant. Rattles have been used for this purpose since antiquity, and experts in child development believe they help the infant improve hand eye coordination by stimulating their senses.
Baby rattles go back at least 2500 years. A rattle made of clay was found in Poland in a grave of a baby who was a member of the early Iron Age Lusatian culture, and was documented by archaelogists. That hollow clay rattle was shaped like a pillow and was filled with little balls. It was found next to a tiny urn containing the cremated remains of the baby. Many similar examples of baby rattles have been recovered from Greco-Roman archaeological sites. Often, these rattles were in the shape of a pig or a boar, and sometimes a figure of a baby was riding the animal. Pigs were associated with the Greek goddess Demeter, who was invoked in rituals intended to protect babies in life and death.
In colonial America, artisans made elaborate gold and silver baby rattles incorporating bells and whistles and teething devices made of coral.  In 1777, in the early days of the American Revolution, John Hancock wrote to his wife, Dorothy Quincy Hancock saying, "I have sent everywhere to get a gold or silver rattle for the child, with a coral to send, but cannot get one." Their daughter Lydia later died at ten months of age.
Rattles can be made of wood, plastic or cloth. Many of the rattles are brightly colored, have animal or flower shapes, and typically make sounds when shaken. These sounds can range from the dull sounds typical of wooden rattles to the jingling or bell type sounds that metal rattles make.
Rattles provide a source of stimulation. Babies like the sounds they produce and follow the path of the rattle with their eyes, as well as giving them a sense of discovery as they try to grab and hold the rattle.
Many rattles have a dual function, doubling as teethers as babies grow. They have textured surfaces which are easy on the gums and provide the stimulation that babies need.
