When we are asking our children to change their behavior or understand the impact of their behavior we are creating neural patterns for them.
If we use punishment we are creating shame, fear and pain connections to the experience of being asked to change or grow.
These neural networks then get activated in other relationships making it hard to be receptive to change or to feedback from people in our lives.
When we use teaching focused methods instead of control focused methods our children can learn without feeling yucky about growth.
Gentle teaching doesn't make weaker adults, it makes calmer more centered adults.
