So I am going to use a pack n play as a bassinet until it is time to transfer to a crib. I bought a thin mattress pad to put on top of the pad. It was the wrong size. How frustrating. So I can either order the one of proper size online and get it by the 12th. The problem....I am having the baby on the 8th and will more than likely be home before Tuesday. Is it necessary to have the 2.5 inch mattress or will a quilted pad over the PNP cushion be enough and an extra mattress is just overkill? The PNP pad just seems so hard.
