'Item four: you must be kind.' I am kind, but extremely firm.
Hmmm...where have I heard this before?
Kindness is important in order to show respect for the child. Firmness is important in order to show respect for ourselves and for the needs of the situation. Authoritarian methods usually lack kindness. Permissive methods lack firmness. Kindness and firmness are essential for Positive Discipline.
I'm not at all surprised that the greatest nanny every (with rosy cheeks, and no warts!) totally gets it. :o)
