Nappers, bassinets and changing tables are all Pack 'n Play attachments that are appropriate for newborns. The average napper is safe for babies 3 months or younger, while a bassinet is safe up to 15 pounds. A changing table attachment can hold a child up to 30 pounds.
Certain Pack 'n Play models come equipped with a napper, a bassinet and a changing table, while some others come with a combination of one or more of these attachments. As of 2015, a Pack 'n Play averages anywhere between $40 and $175, according to howmuchisit.org. A Pack 'n Play with more features typically costs more than one with fewer features.
Some bassinet or napper attachments come with soothing vibration, music or sound settings to help babies sleep. They are also usually well-padded to allow for more comfort. Some bassinets are removable to use as standalone beds, while others are only good for use while attached to the Pack 'n Play. Once babies outgrow the napper or bassinet, they may sleep on the padded mattress, which adjusts to various heights based on the age of the child. Certain Pack 'n Play models come with additional storage cubbies for diapers, wipes and other essentials.
