A bedding for babies and infants includes two mattresses, wall-surface cushion materials, and handles. The two mattresses have mutually opposite sides that are coupled and have square shapes in planar views of the two mattresses. The wall-surface cushion materials are removably mounted on top surfaces of other three sides excluding the coupled sides of both the mattresses via coupling members. The handles removably mounted on both the mattresses or the wall-surface cushion materials. The wall-surface cushion materials are separably and mutually coupled between the adjacent wall-surface cushion materials via coupling members. The bedding for babies and infants is configured to be carried around with the handles in a state where both the mattresses are folded such that top surfaces of corresponding wall-surface cushion materials are abutted to be closed with a coupling member.
