What is their level of self-awareness?
Part of strong parenting is having a reasonable level of self-awareness. An awareness of how you interact with your children and the behaviors that you model in their presence is important. It means recognizing when a particular parenting approach is not working and trying something different. It also means being self-aware enough to realize that you are not perfect and not being too proud to apologize to those kids when you inevitably mess up or lash out.
