I agree with the other parents in this thread. It's easy to tell who they are! 1) Congrats! Becoming a parent is a really wonderful phase of life.
2) From now on your kid will always be the most important thing in your life, period. More important than your gear for sure, and even more important than your wife. She'll eventually agree with that too if she doesn't already.
3) Personally, I went to replace my B&W 802M on SoundAnchor stands with their bottom woofer dust caps at eye-level with something smaller (805M + sub so I can have a respectable-if-older surround system in future) on weighted stands. By the time I got around to filling the stands, my son had learned not to touch the 802s. So they still sit where they started out.
4) I did install a large piece of Plexiglas-type material in a wood frame across the front of my system. That's been a huge help to keep his little hands out. Now he can reach the top of it but still leaves it alone... for now.
5) As the other parents here have pointed out, start thinking about how to secure your large speakers (and EVERYTHING else) from falling on your child. Sure it's fun to joke about protecting the speakers in various cruel ways but your mindset will eventually morph into seeing things as a parent whose job it is to protect the child from dangers. This is no one else's responsibility, quite a large realization as a new parent if you ask me.
Babyproofing is challenging and fascinating unto itself, but is nice because it goes in phases. Do you need to secure the kitchen drawers when they can't yet stand? Nope. Should you watch your child's development and sort out in your head what might need doing next? Yes! Should you crawl around on the floor with them to see things from their perspective? Yes! And bring a vacuum, Swiffer, etc. with you. Good luck!
