Co-sleeping off the top of my head: head at boob level, keep pillows away, duvet below your waist, position yourself on your side in a C shape around baby, DO NOT DRINK OR SMOKE
I got 5 hours out of R by putting him on his front, he's basically comfortable in the same position I am, on my right about 3/4 flat! Will try him in the crib when we get home tonight :o
