Study Notes
Infancy: The Shortest Developmental Period
- The shortest period of development, lasting approximately two weeks. It marks a transition from uterine life to the external environment.
- It is divided into two stages:
- Partunate period: From birth to 15-30 minutes after birth, when the umbilical cord is cut, and the infant is still dependent.
- Neonate period: After the umbilical cord cutting, the infant is independent and needs to adjust to the external environment.
Infancy's Radical Adjustments
- Infancy is a significant transition, moving from an internal to an external environment. This requires adaptation, which might be challenging for some infants.
A Developmental Plateau
- The rapid development during the prenatal period slows down or even regresses slightly during infancy. This is normal and usually lasts for a few days or a week.
- Infants typically return to their birth developmental level by the end of this period.
A Preview of Later Development
- While predicting future development from birth is difficult, newborn development provides clues about what to expect later on.
Hazards of Infancy
- Infancy is a hazardous period, both physically and psychologically.
- Physically: The need to adapt to a new environment leads to difficulties and a high infant mortality rate.
- Psychologically: This period is critical for forming attitudes toward the infant. Attitudes established before birth can change after birth but are sometimes reinforced.
Adjustments of Infancy
- These adjustments are crucial for survival and resumption of development:
- Temperature Changes: The constant temperature of the uterine sac (100°F) is different from the varying temperatures outside (60-70°F).
- Breathing: Infants must learn to breathe on their own after the umbilical cord is cut.
- Sucking and Swallowing: Nourishment shifts from the umbilical cord to sucking and swallowing, which are underdeveloped at birth. This can lead to weight loss.
- Elimination: Waste elimination through the umbilical cord stops, and infants must learn to use their elimination organs.
Influences on Infancy Adjustment
-
Prenatal Environment:
- A healthy prenatal environment contributes to smooth adjustments to postnatal life.
- Neglect or poverty during pregnancy can create unfavorable conditions in the uterus, negatively affecting postnatal development.
-
Birth Environment:
- The birth environment, including the medical intervention and the support provided, can affect the adjustment process.
-
Postnatal Environment:
- The support system, affection, and care received after birth play a significant role in the infant's development and adjustment.
