Child Damage Mitigation

Watching a toddler is like nailing Jello to a tree. My daughter liked to "adjust" the settings on my subwoofer in my home theater system. I just made sure I wrote down what they were so I could put them back. Still have the same system now. She will be graduating from college soon. She is doing very well. My 25 year old ht system works just fine too.

My daughter had zero issues with my hifi rig as she wasn't crawling or later toddling around without an adult watching her as should be the case with any little kid...that's simply called parenting, and it's not that difficult.

Correct the child ,if they do something wrong ,it’s not rocket science .
in mybaby boomer generation.
you are not taught any of this liberal BS 
about if it may hurt your feelings ,yes or no ,youjust have to be persistent if thst means raising your voice , or a talon the hand so be it get the message across.
i trained my kids,as well as cats and dogs none of them go behind the stereo ,all will sit on the couch and listen and enjoy the music .being consistent is the key ,

Kids:
never wanted any
didn't have any

Regrets:
none

Because of the times (this too shall pass, but not w/out a lot of damage) and the fact my driveway is 800' long I bought 50 large steel tire spikes. Those are welded double xs that leave a very sharp point upright no matter how you toss them.  In your case bird spikes on a strip would also work.  Just surround your equipment with either of these and after crawling through your security perimeter once, I don't think they will go there again.  Please be sure your local ER is in your insurance system.Best wishes to allMark
