No specific suggestions, but I feel for you. Pretty much the same situation at my home. 3 year old is now fine, but the one year old can't be taught. My stereo is in the living room so it's a constant temptation for them because that's the room the kids are always in. I always suspect that the posters who get on their high horses and suggest raising one's kids properly have a different layout to their home or bigger homes where the kids aren't in such close proximity to the hifi
When I had an amp I basically put it away for a year or two and replaced it with something cheap that I wouldn't care if it got trashed (it didn't). One of the reasons I bought the Genelecs is the metal grill protecting the drivers that can't be removed.
No high horse here, and when they were very small we had a small lounge with all that kind of stuff in. Like I said, they were simply told what was what. That way, we didn't get any greasy fingerprints on the tv, no fruit or toast in the bluray/dvd player, and no tweeter mishaps....
