Ugh. I'm sorry. I don't know why this got under my skin tonight (although, in my defense, no matter what mood I'm in I'm baffled by this one). BUT why, why, why??? In another thread I just saw the question was something like -- is co-sleeping hazardous after all? And the reason it was asked, because baby fell from a normal-highted bed. Well, NO, co-sleeping is not hazardous. But sleeping with a baby in a bed that is high off the ground (even the hight of a normal bed) is! Sure, babies survive it. But jeez, why not put it on the floor? Why is it that people are so resistant to putting their mattresses on the floor? I have had mine on the floor for over nine years now. I'm looking forward to the day that I can sit on my bed and have my feet on the floor with my knees at a 90% angle. I think that'll be nice! But not so nice that it was more important than having my baby safe in the bed.
I think it drives me crazy because I do think it can be dangerous for baby to fall out (though, it is true that I have never heard of a real serious injury), and I think co-sleeping gets such a bad rap so I wish we could at least take some easy precautions that will make it safer, yk? Mattress on the floor should be right up there with rules like don't sleep with baby while intoxicated, don't put baby in the crack between bed and wall, don't put pillows all around tiny baby's head. Why not?
Plus, even if it's not horribly dangerous (if that is the case), babies shouldn't have to find themselves hitting the floor in their sleep every once in a while.
