Within the stages of the development of pregnancies, is the perinatal period, the one that begins in the twenty-eighth week of management, and ends seven days after delivery. During this stage, the baby's organs are more developed; being, even, capable of detecting sound waves that come from outside. Births that occur under this specific time can be dangerous if they are less than 37 weeks pregnant, since the fetus, although it already acquires important abilities, is not yet fully developed; According to WHO studies, the rate of perinatal deaths has increased in recent years, due to the increase in adolescent pregnancies.
At 28 weeks of pregnancy, the fetus, which can perceive its mother's voice much more clearly, begins to perform a series of tensing and distending movements of the hands and feet. This is an indicator of a baby who has the grasp reflex, the one that makes them contract their hands when trying to extend them. The skin will protect much more fat and will be covered with a substance called vernix, which gives them the typical reddish color at birth. In week 35, the mother begins to transfer a kind of temporary immunity against certain diseases to the baby; this is the reasonwhereby vaccines are not given to infants until they are 15 months old. The mother, for her part, due to the proximity of delivery, may experience episodes of anxiety, in addition to an increase in appetite.
