According to the theory of "fourth trimester", Human beings are born three months in advance. According to her we were born only with enough maturity to survive.
Dr. Harvey Karp is the author of the book "The happiest baby in the neighborhood" and the creator of the fourth quarter theory. With this Karp explains the common problems that babies have in their first months: colic, anxiety and sleep problems.
For Karp it is simple: babies are unhappy at this age because they have lost their mother's womb. He believes that instead of trying to teach newborns about the world, they should simply provide a cozy and uterine-like place.
While many other mammals are born with various survival reflexes and instincts that allow them to remain or run the moment they are born, the human baby begins life with only a few, although vital, only guarantees survival. They are the reflexes related to breathing, sucking and swallowing.
Compared to other animals, the human baby is born relatively immature and relies heavily on his parents to survive. Perhaps this is due to the fact that the human infant has no predators, and therefore does not need to flee in order to protect himself. In the first trimester of life, the baby suffers from irregular breathing, small tremors and are vulnerable to adapt to life outside the uterus. At the end of the third trimester, however, the baby becomes a more conscious and able to respond child.
When considering the difference between a minute of age of the newborn and a period of three months old baby, the growth and development rate that a human baby experiences in its first twelve weeks of life is exceptional.
Research has found that the greatest growth of the brain occurs in the uterus especially in the third trimester and immediately after birth.
These evidences inspired the American pediatrician Harvey Karp to investigate and develop the concept of the "Fourth Quarter."
But what is the reason why baby is born at 40 weeks and not at 52? The author considers that the main reason why babies enter this world at 40 weeks is to ensure a safe delivery.
