I bought this product for my son who loves to be swaddled and held but has started to roll over. We have tried many tricks to get him to sleep without the swaddle with no luck. The first time in the zipadee-zip I watched him startle on the monitor and immediately go back to sleep. So far it has soothed our non-napping son, helping him sleep longer! Part of our order wasn’t shipped so I contacted the company support, they were extremely apologetic and that day they shipped the piece to me with expedited shipping.
