True that seems to be low-risk, and 9-5 cubicle might not be family friendly either. But I'm working for a company where I can choose my own hours to a certain degree (in between 8-12, leave after 8 hours with one hour break). So I can be home rather early.
Plus work from home means that I can easily take care of making dinner etc.
But I didn't consider a consulting business and actually I have no idea how your day looks like in that area. Care to elaborate, I'd love to hear about it :-)
