A chrome extension that deletes babies from your newsfeed permanently--by replacing them with awesome stuff
It's pre-set up to replace them with cats, but if you hate cats, it's easy to change it to pugs, or girls, or whatever you're into. Or use your own RSS feed, like Nasa's POD.
You can also add your own keywords to trigger the removal. It's not going to be perfect, so adding a baby's name might help. Hopefully this will spark conversation and change when you post about it on Facebook.
