A diaper changing device utilizes a baby supporting member having a supporting surface on which a diaper is to be positioned, naps extend outward from the supporting member and are configured to be foldable over the diaper placed on the supporting surface to maintain the diaper in position on the device. Straps are provided to circumscribe the leg of the user, i.e. the diaper changer, and to maintain the device on the changer's leg. Once the device is secured on the user's leg, the baby is placed on the diaper. The diaper is then wrapped around the baby and secured, all while the baby is positioned upon the device.
