I have 3 boys, ages 11, 14 and 17. I find the best audio 'tweak' is duct tape. Inexpensive, and worth every penny.
Seriously, you will need your wife to understand how important this hobby is to you. If she stays home with the children, like mine did, she can teach them from the time they're in diapers, what is 'not to be touched'. I've never had any problems (knock wood). My wife knew that my gear was expensive, she didn't want me to spend more money, so she had a vested interest in helping to protect my equipment.
