I'm not the person you replied to, but I'm in the same situation. My wife and I have two daughters, ages three and eight. My wife stays home and I go to work.

I'm not the person you replied to, but I'm in the same situation. My wife and I have two daughters, ages three and eight. My wife stays home and I go to work. I would change places in a heartbeat if it made sense. It's not really an option for us because my earning potential is so much higher. We're beyond the window of time where we could make that change in arrangement without a major life upheaval. For what it's worth though, my wife supported me entirely for a few years in our early twenties. Neither of us liked that arrangement very much, so when we had the opportunity to swap we did.
