Many parents of newborns elect to bring their infants into bed with them during the early months. This Sleeper addresses a concern that many parents have when co-sleeping and that is keeping baby safe. Consider your concerns abated. For mothers who had a c-section, having the baby right next to them eliminates the need to get in and out of bed during the night. One of the best reviewed features of the Rest Assured Sleeper is the small vibrating/music/night light box. The music is very soothing and automatically shuts off. Several parents told us that they would take the box with them to attach to the car seat handle or stroller. Finally we come to the mattress which got thumbs up for being thick & soft.
