I have a question for those that use the rock n play. I planned on using this next to the bed for DD to sleep in for the first few months. We just recieved it at our shower and I put it together. I'm just now noticing that it has buckles/harness. We had also planned an swaddling as I've heard it helps LO sleep. My question I can I use both and just not buckle her in? Or is it one or the other? Thanks!
