Small children and complex audio systems do not mix. Once a child attains a certain level of mobility, their natural inclination is to poke, grab at, slobber on, pull at, bite, etc. It's not a question of good/bad parenting. In most interactions between a child and an audio system it is the system that will sustain the damage. However, given the sharp edges, high heat and heavy weight inherent in most audiophile designs, there is always the potential for injury to the child. The solution is to prevent the child from having access to audio system. It maybe inconvenient, but it is foolproof.
