Get started for freeSummarize the role of nutrition in the physical development of infants, including the benefits of breastfeeding. Adequate nutrition is essential for physical development. Malnutrition and undernutrition affect physical aspects of growth and may also affect IQ and school performance. Breastfeeding has distinct advantages over bottle-feeding, including the nutritional completeness of breast milk, its provision of a degree of immunity to certain childhood diseases, and its easy digestibility. In addition, breastfeeding offers significant physical and emotional benefits to both child and mother.
Identify the milestones of gross motor and fine motor skill development in infancy. The development of gross and fine motor skills proceeds along a generally consistent timetable in normal children, with substantial individual and cultural variations. In the 1st year, advances in gross motor skills allow children to roll over, sit upright without support, stand while holding onto something, and then stand alone. A child who grasps an object with thumb and finger at 8 months may hold a crayon adaptively at 11 months, and imitate strokes on paper by the age of 2
Describe how the nervous system and brain develop in the first 2 years of life, and explain how the environment affects such development. The nervous system contains a huge number of neurons, more than will be needed as an adult. "Extra" connections and neurons that are not used are eliminated as an infant develops. Brain development, largely predetermined genetically, also contains a strong element of plasticity-a susceptibility to environmental influences. Many aspects of development occur during sensitive periods when the organism is particularly susceptible to environmental influences.
Explain how the reflexes that infants are born with both protect them and help them adapt to their surroundings. Reflexes are unlearned, automatic responses to stimuli that help newborns survive and protect themselves. Some reflexes also have value as the foundation for future, more conscious behaviors.
Describe how information-processing approaches explain cognitive development in infants, and summarize the memory capabilities of infants in the first 2 years of life.
