In the mother's womb, the child was warm and comfortable - there was always one and that burns the temperature, constantly to the baby came oxygen and all the necessary nutrients. The baby was protected from external influences and injuries. In the womb the kid did not see anything, because it's absolutely dark, the lungs did not work, just like the digestive tract.
And finally, the child was born. At first he does not hear anything, because there is still liquid in his inner ear. But the bright light he catches, and he irritates his eyes, accustomed to the darkness. The tender infant skin is exposed to various touches, they seem extremely unpleasant to the baby. After giving birth, the baby is exposed to a huge temperature drop, it's just like if we were stripped suddenly, doused with icy water, and even kicked out to the frost. In the lungs of a baby's broken lungs, air rushes, straightening them and causing them to breathe, this also causes severe pain to the newborn. After the first desperate, loud cry, the baby begins to breathe on his own. the first sigh is very important, because it provides breathing to the brain, which can not exist without oxygen. The baby's breathing is established within five minutes after it was born.
The first days of a newborn's life are a very important time when all the systems of the body are rebuilt, all the mechanisms and functions that "slept" in the mother's womb begin to work. The kid now must breathe himself, adjust the temperature of the body. Soon the baby's skin turns pink, as his blood circulation is improving.
Such adaptation of a newborn in the first days of his life is not easy, even if the birth was quick and without complications. The first adaptation phase of the newborn lasts three hours after birth. At this time, his mother's hormones still predominate in his blood. In the second phase, the parent hormones gradually decrease, are replaced by the hormones of the child. In the third phase (approximately on the 5th day after birth), the maternal and own hormones in the child's blood gradually decrease.
In the first days of life a newborn can lose weight, change skin color, stool. Such changes quickly pass, they are considered transitional physiological phenomena.
A child born after the 38th week of pregnancy is considered full. The body weight of full-term boys is on average 3,400-3500 grams, of girls 3200-3400 g. In the first days of life, babies lose weight because of starvation and loss of water with sweating. And even intensified feeding does not stop this process. The body weight is completely restored to the 6th day after childbirth. The child will quickly gain weight, if it is often applied to the chest, give him a drink between the feeds, observe the thermal regime.
Premature babies last longer than donors adapt to the surrounding conditions of existence. The periods of their adaptation are much larger, their condition can significantly worsen during the adaptation period. Premature babies lose large body weight and are more difficult to restore than full-term babies, so they need more care and more frequent feeding.
Thus, the first days of a newborn's life - the time when kids need constant attention and care. Mom should be at this time nearby and provide the baby with everything necessary.
