When I was registering for items for Fetus Fix (aka Rock), I wanted to get him a swing, but I didn't want a huge monstrosity taking up half of our living room. So, when I found this puppy, I fell in love. It's made by Graco and you just plop your car seat into it. When you aren't using it, it folds up flat. Brilliant! Too bad Rock HATED his car seat and thus he never wanted to swing. Fast forward to Louisa. She only hates her car seat when it's not moving. And she LOVES her car seat when it's swinging.
