Bed sharing/co-sleeping

Emily
Something that I've been wanting to try for a few weeks now but still haven't had the courage because I am so afraid of the worst happening. 
If you bed share or used to, please share your advice, and safe tips. It's all welcome. If you're opposed to bed sharing, I respect that. This however is my decision and I'm just seeking help on how to make it as safe as I can. Thanks in advance :)
