Bed sharers: When did you start? Safety tips?

Andrea

I have a 1mo who currently sleeps in a soother/bassinet next to me but I would rather bed share and it seems like he prefers it too; the few times I let him in bed with me we both slept so much better and for longer stretches. However I'm scared to commit to it because I've been told so many times how risky it is. any thoughts? Advice? Cautionary tales?
