A sleeping infant positioning device that will hold an infant in the recommended back-lying position while in a crib or other flat surface. The device includes a pad that has an attached fabric and strap safety restraint, into which the infant is placed. The restraint is designed to fit over roughly the area where a pair of diapers would fit over the infant, with the restraint also including a pair of leg holes to allow insertion of the legs of the infant. A pouch is located on the pad behind where the infant's head is placed, allowing placement of a pillow if desired. An adjustable blanket can also be clipped to the pad, allowing the blanket to be placed over the infant if necessary.
