Once Zoey grew out of her co-sleeper, we put her on a twin mattress on the floor surrounded by pillows. This was easier, since she would wake up anytime we tried to put her down in the pack and play. (we have been staying with in-laws and decided to wait to move ....any day now....before buying a crib)

With a floor mattress, I can side lie-nurse with her and get into a sitting position and slowly lower her down onto the mattress without straining my back or jostling her too much--it's been great!

Do I need to get a real crib? She's definitely moving around alot more these days, but thought that a bunch of cushioning around the mattress will suffice....no?
Is there an alternative.....like one that sits on the floor?
