I have the Motorola video monitor. Right now I keep it on the corner of crib, but don't have it secured down. Sometimes when my son rolls too much it falls onto the floor. It's only happened a few times, but I'm nervous it's going to fall on his head next time. Also, now with the crib at its lowest point, if he rolls into the corner under where the monitor is I can see him at all. Any suggestions on where/how to mount monitor where it is secure and I can see him wherever he is in crib.
