Hey we started using a mattress on the floor maybe 2 weeks ago.... first thing that happened was that I was suddenly able to settle her without BB - dummy and a cuddle and she was back to sleep. Then she dropped from waking twice a night, to once a night and the last two nights she has slept through till 5am or 6am! Better for me too cause I can just lie down with her, don't have to get her out of bed or put her back in! Worth a shot!
