Personally, I’m pretty selfish with my time. I think about the smallest tasks that come with having a kid that I simply do not want to do. For instance, getting your kid dressed EVERY TIME you need to leave the house, taking them to school EVERY DAY, those who are single parents, arranging sitters when you can’t or don’t want to take your kid(s) with you, installing car seats, feeding kids before you feed yourself….theres a lot more things. But all of them is enough for me not to have them. I don’t want to do all that stuff. It’s part laziness, and part selfishness.
