Study Notes
Comparison of Prenatal and Postnatal Life
- Newborns regulate body temperature by increasing activity in colder environments.
- Environment: Fetus lives in amniotic fluid; after birth, transitions to air.
- Temperature: Prenatal temperature remains constant; postnatal temperature fluctuates.
- Stimulation: Minimal sensory stimulation in utero; postnatally, all senses experience various stimuli.
- Nutrition: Prenatal nutrition is maternal blood-dependent; postnatal nutrition requires digestive system function.
- Oxygen Supply: In utero, oxygen is transferred via the placenta; after birth, it is absorbed through the lungs.
- Metabolic Elimination: Wastes are passed into maternal circulation pre-birth; post-birth, they are eliminated through skin, kidneys, lungs, and gastrointestinal tract.
States of Arousal in Newborns
- Newborns cycle through six states of arousal affecting sleep and wakefulness.
- Regular Sleep: Full rest, little activity, 8-9 hours.
- Irregular Sleep: Gentle movements, occasional stirring, 8-9 hours.
- Drowsiness: Transitioning states, varies in duration; eyes may open with a glazed look.
- Quiet Alertness: Eyes open and attentive, relatively inactive, lasts 2-3 hours.
- Active Alertness: Frequent uncoordinated movements, 2-3 hours; breathing is very irregular.
- Crying: Associated with waking activity, 1-2 hours; involves vigorous motor activity.
Sudden Infant Death Syndrome (SIDS)
- SIDS is the unexplained death of an infant under 1 year, commonly occurring between 1-4 months.
- Possible causes include biological defects, exposure to smoke or caffeine, and sleeping on the stomach.
- Genetic links include heart rhythm regulation genes and liver enzyme defects.
- Impaired brain receptors may prevent babies from waking when breathing is restricted.
- Risk factors: stomach sleeping, soft sleeping surfaces, and lack of pregnancy/birth education.
- Urban African American infants face higher SIDS risk due to less accurate sleep position advice post-delivery.
Medical and Behavioral Assessment
- Newborn assessment is crucial shortly after birth; the Apgar Scale is widely used.
-
Apgar Scale Signs:
- Appearance (0-2): Blue, body pink, entirely pink.
- Pulse (0-2): Absent, slow, rapid.
- Grimace (0-2): No response, grimace, crying.
- Activity (0-2): Limp, weak, strong.
- Respiration (0-2): Absent, irregular, good.
- Each sign is rated between 0 and 2, with a maximum score of 10 indicating health.
Reflexes and Development of Motor Skills
- Most reflexes disappear in the first 6 months as voluntary control develops.
- Reflex adaptations suggest a foundation for purposeful behaviors.
- Resilience of specific reflexes, like palmar grasp and stepping, aids in motor development.
- Stimulation of stepping reflex can accelerate independent walking.
- Reflex assessment is critical for diagnosing potential brain damage or neurological issues.
Brain Development and Experience
- Brain growth spurt begins in the third trimester and continues until age four, facilitating major milestones.
- Rapid brain development underlies critical sensory, motor, and cognitive skills.
Language Development Milestones
- Birth: Responses to sounds; crying communicates needs.
- 1.5 to 3 months: Coos and laughs emerge.
- 3 months: Interaction with speech sounds begins.
- 5 to 6 months: Constant sound production; mimicking sounds.
- 6 to 10 months: Babbling develops with consonant-vowel strings.
- 9 months: Begins word understanding and sound imitation.
- 10 months: Loses discrimination ability for non-native language sounds.
- 10 to 14 months: First words and sound imitation begin.
- 16 to 24 months: Rapid vocabulary expansion from 50 to 400 words.
- 36 months: Vocabulary grows to up to 1000 words; grammar approaches conversational norms.
Pre-Speech Development
- Infants produce cries, coos, and babbles before uttering first words.
- Pre-linguistic speech indicates sound differentiation capability.
- Sound differentiation starts to diminish by 9-10 months as meaningful speech comprehension develops.
- Crying becomes the key communication method, with parents often distinguishing between different cries.
