There is a large gap between not wanting to do it full time and not wanting to do it at all. I"m certainly in the former camp, and as opposed to OP my wife makes more money than me, so it would make even more sense. But I know I would be unhappy doing it _full_ time. To the point, I would not take a job that did not afford me morning, evening, weekend, and occasional PT time to spend with my kids. I enjoy being heavily involved in their day to day rearing. I just don't want to abandon my (enjoyable) career if its not necessary.
