I just put a water proof pad on my bed tonight, and I thought I would pass along the tip. One of my coworkers had her water break while she was in bed and it ruined her mattress. My water broke in bed too with T, but I had heeded my coworker's warning and laid down a pad, so no harm was done. I think relatively few women have their water break first, and also relatively few get a huge gush, but it's such an easy precaution to take that I thought I would mention it. If you have a water proof pad that you got for the crib, think about laying it under the sheet on your side of the bed to protect your mattress, just in case.
