My hubby works in emergency services, and attended a co-sleeping death of a 6 week old bubba a few nights ago. Needless to say it was devastating for all involved. I can't go into details except to say the mother was not under the influence of drugs/alcohol. But I just wanted to put it out there that deaths do occur to the very best of mothers. Women who are simply exhausted and doing the best that they can. I know, I co-slept with all 3 of my children on occasion myself. I guess what I am saying, is please do it as safely as you can - there are lots of guidelines around to make co-sleeping (bed-sharing really) safer. And please remember that many women in countries around the world do co-sleep/bed share, but they dont have the luxury of comfy beds and squishy pillows that we do.
I know some may be offended by this post, but given the number of bed-sharing accidents my husband has attended over the years (that naturally the general population don't hear about) I feel I have to say something
