Vastsündinu

Vastsündinu refers to a human infant from birth up to approximately one month of age. This period is a critical transition from intrauterine life to the external environment, marked by significant physiological and behavioral adjustments. Immediately after birth, the newborn's first priority is to establish independent respiration. They typically cry spontaneously, which helps clear their lungs of amniotic fluid. Their skin may appear bluish initially, especially the extremities, due to immature circulation, but this usually resolves quickly. Vastsündinud have a range of reflexes, such as the rooting reflex (turning the head towards touch on the cheek to find a nipple) and the grasping reflex (clutching a finger placed in their palm), which are essential for survival and bonding. Their senses are developing; they can see at close range, respond to sounds, and have a developed sense of smell and taste. Sleep is a dominant activity, with vastsündinud sleeping for 16-18 hours a day in short, irregular cycles. Feeding is another primary concern, usually through breastfeeding or formula, crucial for growth and development. The vastsündinu is entirely dependent on caregivers for all their needs, including feeding, warmth, hygiene, and protection. This initial month is a period of rapid growth and adaptation, laying the foundation for future development.
