I am currently expecting DC#2. I have been doing research on neccessary items. I keep seeing everyone say that the rock n play is great! Can someone explain what it does? Is it just a rocker? Does this replace a swing? Is this something you would purchase if you also had a 22 month old when you had your new LO?
Sorry for so many questions, I just want to learn about this from real people who have used it and not the generic store explanation.
