Well, I totally understand the people to make a deliberate choice of not having children. It is such physically and emotionally charged task. I would say it is impossible to do it right. Infants, middle schoolers, high schoolers… It is not easy for kids to be kids, to depend on parents who are also struggle with their problems and issues. The issues of communication, balancing, keeping priorities are especially importance in the relationships with your middle school children: it is critical time to form your lifelong relationship with them and, probably, it is one of the most challenging period.
