Re: crawling and bedsharing?
With my sons, this is when we started transitioning them to their own beds when I wasn't with them. So for naps, or the first part of the night, they slept in a crib, and then slept the rest of the night in bed with me. We always woke up at the same time in the morning so that wasn't a problem.
My daughter screamed at the sight of her crib, so we taught her to get off safely, and put pillows on the floor next to the bed in case she did fall off (it happened once or twice, but more like her trying to get off the bed and sort of just sitting down as she got off)
It helps that our master bedroom is right off of the dining room and kitchen where I spend most of my time. So 99% of the time she called out to me when she woke up, and I would go in right away to find her just sitting on the bed waiting for me.
If I were not nearby, or she would be spending a lot of time there without me, I would probably try and put the mattress on the ground.
