PC- sleep is awfully elusive in the beginning anyway. But, the comfort/knowledge that my little worm was within arms reach brought me alot of peace. In fact, I think one of those co-sleeper things is called "Arms reach" or something! And, you may change your mind/arrangement with time, too. Before birth, I was adamant that Jonah would sleep in a crib from moment one! We had to do a pit stop to the Toysrus on the way home from the hospital (with a broken bone in my pelvis, no less) cause I freaked out about him sleeping in a crib away from me! My thoughts changed so much after I had him. ")

What I did was remove all padding from my bed (I had a feather tick that I slept on), as well as all pillows but one- mine. I then built a barricade on the far side, which I later converted to the bed rail thing that Jonah has on his own bed right now. (When we slept at my fathers a few weeks ago, Jonah fell out of bed!)

I am a really light sleeper, and it was just he and I in bed. So, that worked for us, but, I can see a heavier sleeper, and a couple, wanting something a bit more distant.
