I'm less convinced about bringing the child to work, mostly because I've never been in a workplace where I've seen that, so it's tough to imagine.
Can you elaborate on that (or do you or a co-worker have a blog post, article, etc. about your experience)? Can you run though a typical day?
I work remotely, entirely, as does my wife. Obviously, this is one way to solve that problem, but it's not possible for most people, and the startup I work with is thinking about setting up offices, etc..
