David C. Pollock said this quote

Caregivers, like all of us, inevitably reflect their culture's attitude toward children and life. The story goes that when Pearl Buck was a child in China, someone asked how she compared her mother to her Chinese amah. Buck replied, If I want to have a story read, I go to my mother. But if I fall down and need to be comforted, I go to my amah. Her mother's culture valued teaching and learning, while her amah's placed a greater value on nurture. Even as a child, Buck instinctively knew the difference.
