Is the difference that with co sleeping the crib is up against the bed and baby sleeps there almost next to parent and bed sharing there is no crib and baby sleeps in bed right next to the mom or dad? Would this make bed sharing " unsafe"? I put it in quotes cuz of the debate about that. I'm asking cuz it seems DS sleeps more soundly cuddled up next to us but then I don't sleep well cuz I'm worried about bumping him or some other thing that could happen... Rolling onto him, etc. What are some ways that people bedshare? I've seen pics of the co sleepers.
