Dr. Harvey Karp reveals an exceptional treasure that all parents seek, an "automatic" switch for their baby's crying. In a groundbreaking reevaluation of infancy, Dr. Karp combines modern science and ancient wisdom to prove that newborns are not completely ready for the world when they are born.

Through his research and experience, he has developed 4 essential principles that are critical for understanding babies, as well as improving their sleep and calming their senses.

In the book, Dr. Karp addresses questions such as: What is colic? Why are most babies more fussy in the afternoon? How can a parent soothe a baby in just a few minutes? Do babies get spoiled? When should a parent call the doctor for a crying baby? How can a parent get their baby to sleep a few more hours?

The Happiest Baby on the Block provides parents, grandparents, and all those caring for children with the tools they need to soothe their babies almost as easily as flipping a switch to turn off the light.
