In the toys-r-us calalogue i saw what looks like a small bed for bub, so that you can co-sleep, without having a fear of hurting or smothering bub. It sits between both parents and is about the size of a bassinette, maybe smaller. The sides are a mesh material so you can see bub and bub can see you. It's only $50 and i was thinking of getting it. Because i love the idea of co-sleeping, but so afraid of rolling onto bub because i'm not much of a light sleeper. So is this still considered co-sleeping?
