Lee Salk quotes:

Being natural and matter-of-fact about nudity prevents your children from developing an attitude of shame or disgust about the human body. If parents are very secretive about their bodies and go to great lengths to prevent their children from ever seeing a buttock or breast, children will wonder what is so unusual, and even alarming, about human nudity.

Being natural and matter-of-fact about nudity prevents your children from developing an attitude of shame and guilt about the human body.

Our children are the gift we give the world we'll never see.

There's no harm in a child crying: the harm is done only if his cries aren't answered. ...If you ignore a baby's signal for help, you don't teach him ndependence... What you teach him is that no other human being will take care of his needs
