A sleep device for newborns and infants that provides a separate but proximate sleep area near a caregiver or parent's bed and at the same level the caregiver is sleeping at for increased visibility of infant and easier access to the infant without the need for the parent to leave their own bed. The sleep device allows for more convenient access to the infant, better ability to soothe and comfort the infant thru close, yet safe contact, and easier access and egress to the adult bed. The sleep device can include a bumper that slopes downwardly in a direction from a rear bumper portion to a front bumper portion so that a rear side wall portion has a vertical height that is greater than a vertical height of a front side wall portion.
