Better yet, buy only non-toxic alternatives. Use Grip 'N Locks or Door Stoppers to keep doors from slamming on little fingers. Keep children out of restricted areas with Door Knob Covers. Use Light Switch Extenders to make it easy for child to reach light switches. Use sand, wood chips, or other soft material underneath to protect children.
Loose rungs are dangerous.
Better yet, have someone steady the ladder. String it up well above head level. Place Plug Locks on loose plugs, Shockblockers over plugged-in plugs. For all your lamps, etc. Keep extras on hand.
