When a 20-year-old says they don’t want to have kids, people often roll their eyes and respond with the classic, condescending, “Oh, you’ll change your mind when you get older.” Those words can sting like lemon juice in a fresh papercut, and, unfortunately, that young person will have to wait about 25 years before people stop assuming that they'll have regrets or suddenly wake up one day with baby fever. But deciding whether or not to have children is a personal choice, or a choice made between two partners, and starting a family is certainly not for everyone.
