I registered for and received both a Rock n Play and swing. Now I am debating whether to take the swing back. I can really see us using the RnP. It's light and portable. We live in a condo and although it's not tiny, the less stuff the better.
The swing was almost $100, and that could go towards more necessary items (diapers!).
So...should I take it back? Or was it so useful to you that you think it's worth it?
