I have an arms reach cosleeper, which attaches to the side of the big bed and gives bub their own sleeping space...you can get them from the aba website mothers direct. BUT dd always ended up in bed with me anyway...I liked the cosleeper being there so she couldn't roll out, and she slept under a blanket with me, while dh had the doona. As for pillows etc, I always slept with her in line with my boob, and then a knee up, so she wouldn't wriggle down. I have never felt fearful of rolling on dd, because you are so hyper aware of them anyway. I didn't put her between dh and I until she was crawling, and by then she could wriggle herself and make herself felt if she was squashed (which never happened). Even now, dh is just as aware as I am, and if he drinks alcohol he has to sleep in the other room. It works for us.

Cosleeping is the best!!!!
