Abstract: This invention relates to an arm restraint for application around the elbow of an infant to restrict movement of the infant's hands from certain areas. The arm restraint comprises a stiffening member formed of flexible plastic sheet material of predetermined dimensions suitable for being formed into a generally cylindrical configuration about the arm of the infant. A washable fabric covering extends over opposite surfaces of the stiffening member and encloses the stiffening member therein to present a soft, clean, washable, nonallergenic surface for contacting the arm of the infant, and is preferably permanently secured to the underlying stiffening member by means of stitching. Securement means is provided on the arm restraint to permit readily fastening the arm restraint in place in a generally cylindrical configuration about the arm of the infant.
