Simulated pregnancy is a way for people (usually teenagers or adults) to experience what it's like to be pregnant. It works by wearing a special belt or suit that mimics the feeling of having a baby inside your belly. You can also learn about what it's like to have a baby by doing activities like reading books about pregnancy, going to classes or seminars, or visiting doctors. People who use simulated pregnancy get to know what it's like to carry a baby, how big a baby is going to be, and how to take care of an unborn baby.
