I’m the breadwinner in the house but I have a job with a home office. While I have to travel a few times a month, I probably spend more time with my son than if I worked in an office 9-5. We never had to drop him at day care or pick him up late in the evening. His pack and play was in my office for the first year and when I travel, my husband is there 100%. I hate the travel but the trade off is worth it, at least for now. I know in my gut and heart I can never go back to a traditional office job.
I don’t think it matters what the exact disposition of income is, as long as everyone is taking care of the family.
