I don't have children, but I know that even as adults a hug makes us feel protected, safe and loved.
When someone we care about hugs us it generates chemicals in our brain that make us feel strong. The same thing happens with smiling. That's why I think it's so important to take time for ourselves, to find spaces where we can meditate on our day, our goals, our daily thoughts.
Keeping our lives in harmony will help us not only to be good parents, but also good neighbors.
