My son (almost 14 mo.) jumps off of everything. He is completely fearless of water, heights or loud noise. I cannot get him to respond when I say, "NOOOOOO!!!!!!" And he has no memory of the last time he fell. Does anyone have this issue? How do I baby proof without getting rid of all of my furniture? When does it end and is there a way to redirect him at this age. Thanks, Sarah
