    Study Notes

    Physical Growth in Infancy and Toddlerhood

    • Newborn average weight: 7.5 pounds, healthy range 5 lbs 8 oz (2,500 grams) to 8 lbs 13 oz (4,000 grams)
    • Newborn average length: 19.5 inches
    • Weight loss in first few days: up to 5% of body weight
    • 4 months: infants usually double their birth weight
    • 1 year: infants typically triple their birth weight
    • 2 years: infants often quadruple their birth weight
    • 12 months (1 year): average length range 28.5-30.5 inches
    • 24 months (2 years): average length range 33.2-35.4 inches

    Body Proportions

    • Newborn head accounts for approximately 25% of total body length
    • Newborn head comprises about 50% of total length in prenatal development
    • Adult head comprises about 15% of total body length

    Brain Development

    • Newborn brain is about 25% of adult weight
    • 2 years: brain is about 75% adult weight
    • 6 years: brain is about 95% adult weight
    • 7 years: brain reaches 100% adult weight
    • Dendrites (connections between neurons): proliferation in first two years, unused pathways eliminated
    • Prefrontal cortex: matures throughout childhood, substantial growth spurt during adolescence, last part of the brain to fully mature, comprising 85% of brain weight
    • Myelin: crucial for nerve impulse transmission, develops dramatically in first few years

    Reflexes and Motor Skills

    • Infant reflexes: automatic responses to stimuli for survival (breathing, body temperature maintenance, sucking, rooting) and other functions
    • Reflex examples: babinski, stepping, palmar grasp, moro
    • Reflexes transition to voluntary motor skills in first few weeks of life
    • Motor development: from reflexive to more advanced skills in a cephalocaudal and proximodistal order
    • Examples: holding head, sitting, crawling, pulling up, cruising, walking
    • Gross motor skills: large muscle group movements (e.g., raising head, crawling, walking).
    • Fine motor skills: smaller muscle movements (e.g., grasping, reaching, pincer grasp).

    Nutrition and Feeding

    • Breastfeeding is ideal for newborns due to colostrum's nutrients and breast milk's changing composition
    • Solid foods introduced at around 6 months old
    • Risks of malnutrition include marasmus (starvation) and kwashiorkor ("disease of the displaced child")
    • Breast milk easier to digest, contains antibodies, and may contribute to better cognitive development in premature and full-term infants.
    • Formula-fed infants experience more diarrhea/upset stomachs, higher risk of ear/respiratory infections.

    Sleep Patterns

    • Infants (0-2 years): average sleep 12.8 hours/day
    • Newborns sleep approximately 14-17 hours/day in the first 3 months
    • REM sleep: about half of an infant's sleep
    • Nighttime waking: a common sleep concern for parents
    • Safe sleep practices (e.g., back to sleep, no soft bedding) critical for reducing SUIDs.

    Cognitive Development

    • Piaget’s Sensorimotor Stage: infants learn through senses and motor skills, six substages (reflexes, primary circular reactions, secondary circular reactions, coordination, tertiary circular reactions, mental representations)
    • Object permanence: understanding that objects continue to exist even when out of sight, develops around 8 months
    • Memory abilities in infants: improving with age, infants remember experiences for weeks/months

    Language Development

    • Language acquisition: a rapid process supported by biological predisposition ("language acquisition device") and social interaction.
    • Stages of language development: from reflexive to holophrasic to two-word sentences.
    • Holophrasic speech: single words conveying complex meanings (e.g., "ju" for juice)
    • Child-directed speech (motherese) fosters language learning

    Sensory Development

    • Sensation: interaction of information with sensory receptors
    • Perception: interpreting what is sensed.
    • Vision: least developed sense at birth, gradually improving, preference for faces, depth perception developing at 2 months
    • Hearing: very keen at birth, preference for human voices, ability to distinguish sounds at 1 month,
    • Touch: acute from birth, critical for development, including pain
    • Taste/Smell: newborns can distinguish flavors and scents

    Emotional Development

    • Key milestones: social smiling (2 months), laughter (3-5 months), fear/sadness/anger (6-8 months), stranger wariness, separation anxiety
    • Self-awareness: emerges between 15-24 months (rouge test)
    • Temperament differences: inborn traits influencing personality
    • Co-regulation: caregiver and child modifying reactions mutually

    Attachment

    • Attachment theory: affectional bond with caregiver critical for emotional development, secure base for exploring
    • Ainsworth's Strange Situation: assessing attachment styles (secure, avoidant, resistant, disorganized)

    Caregiving

    • Caregiver's influence: responsive and sensitive caregiving crucial for emotional regulation, attachment, and overall development
    • Temperament & parenting style: goodness-of-fit critical for healthy development

    Immunizations and Health

    • Prevention of communicable diseases: Immunizations, including herd immunity, critical during infancy's frequent exposure to various germs.
    • Importance of breastfeeding: to establish critical nutrition and immune system protection for a newborn.
