We never had that problem when mine were younger but we were petrified they would pull TV down on them so those and all dressers were safety strapped to walls. As far as TV mounted on walls. We have all of the bedroom TV's mounted. After mounting you go to HomeDepot(or where ever) and buy the piece that covers the wires(paint it the same as wall) and it looks pretty nice. Hubby is gone right now or I could tell you exactly what it is called(maybe somebody hear knows). Hope this helps. At 3 years old he should be able to be taught to leave TV alone(just another idea) but I know how boys are, LOL
