With our daughter now sitting up and the crawling stage just a few short months away, my wife and I have been babyproofing our home in a big hurry. We've attached the bookcases to the wall and are now securing the kitchen. And I've got to say, I love these magnetic key locks from KidCo used to secure cabinet doors. They install without tools and drilling, are invisible from doors' exteriors and, once in place, the cabinet can only be opened using a magnetic key. They are available for purchase on our site.
