Quotes from book
The Common Sense Book of Baby and Child Care

Name: The Common Sense Book of Baby and Child Care
Author: Benjamin Spock

“The more people have studied different methods of bringing up children the more they have come to the conclusion that what good mothers and fathers instinctively feel like doing for their babies is usually best after all. All parents do their best job when they have a natural, easy confidence in themselves. Better to make a few mistakes from being natural than to try to do everything letter-perfect out of a feeling of worry.”
