We can all agree that regret is a negative thing.. however when it comes to this topic, it’s better to regret not having kids. 1) when you regret NOT having kids, it only negatively affects you, and maybe your spouse is you have one. Besides, there’s always adoption if you can’t reproduce anymore. 2) when you regret having kids, it negatively affects you, your spouse if you have one, AND your kids. And that will reflect in your parenting. Once you’re a parent, you can’t go back.
