My wife has some severe challenges (hormonal and otherwise), so I have changed almost all diapers, and work part time/nights as a software developer purely for the fact that I need to be available to take our child regularly throughout the day, at one point I was full time childcare and job. My wife has a free pass to go on day trips and climbing excursions for her mental health. I guess the point is, to find someone who genuinely wants to help and participate, and find something that works for you. It's such a huge part of life, it's important to get the balance right. That's a difficult thing to do, but knowing what someone's core beliefs about family, responsibility, and expectations is important.
