Abstract: An article or apparatus is described for restraining a baby. The article may include a special-purpose sheet, restraint(s) such as strap(s) that are anchored to the sheet and/or to a mattress, and connector(s) such as buckle(s). The sheet is designed to have a plurality of attached bases that allow the restraints to be anchored to the sheet and/or to the mattress. The baby may be placed on the sheet on his back, the restraints may be lightly tightened around the baby, and the connectors at the ends of the restraints may join to lock the baby on his back. The connectors may then be unlocked in the morning so that the baby may be safely retrieved from the sheet. The sheet may also include strap(s) that wrap around the mattress and connect in the front or back.
