Correct option is A
The period of infancy can be defined differently depending on the context. In some cases, the period immediately following birth, specifically from birth to 2 weeks, is considered a crucial stage for the early development of newborns. During this initial phase, newborns rely heavily on reflexes, such as sucking, and their bodies are adjusting to life outside the womb. This time is important for immediate physical adaptation, like breathing and temperature regulation.
Information Booster:
- Newborns experience rapid physical changes, including the adaptation to air breathing and digestive functions.
- Reflexes, such as rooting and grasping, help babies adjust to their new environment.
- This period is characterized by the development of basic physiological functions, such as feeding and crying for communication.
- The central nervous system begins to mature as reflexive actions dominate the infant's movements.
- The immune system begins functioning independently after birth, relying initially on maternal antibodies.
- Emotional bonding begins, and newborns may show early signs of attachment to their caregivers.
