Is Co-Sleeping a good thing?

I have very strong emotions on the topic of co sleeping. though It is not common for a parent to fall asleep on their child It does happen. You think It will never be you. But It does happen. It happened to me. My son ped away 6 years ago because of this reason. I miss him everyday and the guilt and the pain me and my partner cope with will never go away. I don't dissagree with co sleeping, but for me I will never ever do that again.
