Is it safe to have a 42 inch or bigger on a flat platform when there are toddlers around (i.e. are they easy enough to topple over or shove off the end), or is it simply safer to have them mounted, or use a stand with a mount?

A toddler running at sufficient speed would have enough momentum to topple most HDTVs I think... but a toddler just standing and pushing would struggle I reckon (unless they were aiming for a career in body building at a young age!)
