My kids are fully grown (27, 25) and moved out when they went away to college (never came back - except to visit). When they were growing up I had music in most every room. Formal family dinners in the dining room included music playing on the dining room system (still do). My primary music system set up in a formal living room, and the other systems were budget or old stuff. I never had a problem with the kids pushing in dust covers or tweeter domes, nor did they try to handle my vinyl/turntable. I don't recall having to give them any admonition either. When they were teens I bought them each their own bedroom system which they still have today. Their systems are cheap Best Buy setups, so they didn't inherit my passion for hifi. They're happy with their ipods . . . .
The worst damage to any of my equipment was the result of my wife using one of my speakers as a plant stand and leaving a water stain on the veneer (ever seen an Infinity Monitor speaker - they make great plant stands!).
