16When the 1 is the parent
As a parent, a 1 sets the standard and expects it met: encouraging when you try, impatient when you do not. Children of a 1 learn independence early and need to hear that they are loved for who they are, not what they achieve.
As a child, a 6 wants to help and to be needed. They thrive on family ritual and can carry adult worries too early; let them be a child.
