Young parenting can have many different connotations. For some people, the term is primarily used in reference to unplanned teen pregnancies. However, in some areas it is very common for women to start having children before or during their early twenties. It can be a sensitive topic because those dealing with it who hadn't planned on it are very stressed. At the same time, people who have chosen to have kids early on may deal with people assuming it was unintentional.
It is true that young parenting can be very difficult. Oftentimes, individuals and couples struggle with finances even before children come into the equation. The situation can interrupt other plans and come before a person even feels like an adult. For that reason, many programs are in place to help young parents cope with the unexpected demands.
At the same time, young parenting when it is planned, can be a rewarding experience. A younger person may have more energy to deal with the demands of a child, in particular as the child grows. While it is quite common for people to pursue careers first and childrearing later, occasionally others find the opposite path more rewarding. For instance, a career may not seriously develop until about the time someone is ready to have kids. If they had had them earlier, then they could be taking on promotions or partnerships as their children are becoming more independent.
