In detail


The newborn baby:

Children in the first four weeks after birth are also called Newborn (newborn). The term infant is often used in the same context. With the difference that the entire first year of life belongs to the infant phase.
Depending on which week of pregnancy (SSW) the delivery takes place, different names are common. Before the 38th SSW one speaks of Frьhgeburten, after the 42nd SSW of Spдtgeburten, or 'transfer'. As an ideal period of birth, physicians view a birth between the 38th and 42nd weeks of pregnancy. Weight and size can be very different. As a rule, the newborns are 35 - 50cm tall and weigh between 2.5 and 4.5kg.
At birth, most newborns keep their eyes closed. In any case, they can not see too much after the birth, because their accommodation (adjusting the Brecht power in the eye, to see something sharp) does not work yet. In addition, the unfamiliar, bright light in the delivery room: even the eyes in adolescence and adulthood react in a sudden light incidence very sensitive and close reflexively. Everything is new at the moment of birth for the child. By contrast, the smelling and listening works very well. The latter even so well that the newborn reliably recognizes the mother's voice.
Newborns instinctively look for the birth very soon after the mother's breast. The first milk is still slightly yellowish, but it contains many important ingredients and antibodies that help build the immune systemand defense against pathogens.
The umbilical cord is usually just abgeklempt and not completely removed, because after a few days it falls off anyway by itself. The navel remains. During pregnancy the umbilical cord connected the fetus to the placenta. As part of the blood circulation of the mother, the fetus receives food and oxygen via the umbilical cord.
