“Had I but awakened from sleep
And called her name, she had heard
It may be, and had not stirred,
That now, it may be, has found
The horn’s sweet note and the tooth of the hound.”

“In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.”
—Alicia F. Lieberman (20th century)
