To quit work
Perhaps you’re married and working, but you don’t like working—or at least you don’t like your job. Having a child could get you out of work, and give you the chance to be a stay-at-home-mom. But first off, is that fair to your partner? If he hasn’t agreed to take on the financial burden of not just the two of you but also a child, you can’t just assume you get to stay at home. Furthermore, you shouldn’t have a child because your other pursuits aren’t making you happy.
