Re: crawling and bedsharing?
I put pillows on the floor or used a body pillow as a bedrail while they were napping. Our mattress is on boxsprings and my DH is 6'2 and doesn't have a problem. I also teach them how to get off the bed as soon as they start crawling. They don't ever do it though- like when they wake from nap, my babies just call for me or cry.
