A stay-at-home dad. He looks after the house and/or kids while she does the breadwinning thing.
Felix got made redundant so he became the housedad to the five kids, the goat, three salamanders, a budgie, five cats from next door and the vacuum cleaner. His wife started a very successful junk mail collection and recycling business. He's never been happier in his life! She's never been happier in her life!
