Study Notes
Birthing Process
- The birth process involves three stages: the first stage of labour, the second stage of labour (delivery), and the third stage of labour (afterbirth).
- The first stage of labour is the longest stage, lasting an average of 6 to 12 hours, but can vary depending on factors like the mother's age and prior pregnancies.
- The first stage of labour begins with uterine contractions and the rupture of the amniotic sac (water breaking).
- Uterine contractions cause effacement (thinning) and dilation (opening) of the cervix, pushing the baby downward into the birth canal (vagina).
- The second stage of labour involves pushing the baby out and starts when the fetus' head and body begin moving through the birth canal.
- This stage lasts approximately 30 to 80 minutes.
- The third stage occurs when the placenta, umbilical cord, and other membranes are detached and expelled (afterbirth). This is the shortest stage, typically lasting only minutes.
Potential Problems at Birth
- Anoxia is a lack of oxygen to the brain which can lead to neurological damage or death.
- Premature birth refers to babies born before the 38th week of gestation and weighing less than 5.5 pounds.
- Low birth weight babies are categorized into two types: Preterm and Small for Date.
- Preterm babies are born more than 3 weeks before their due date.
- Small for date babies are underweight even if close to their due date, having experienced low growth as fetuses.
Physical Growth and Development in Infancy
- Cephalocaudal pattern: Early growth occurs at the top (head) with physical growth gradually progressing downward.
Brain Development
- Continued myelination and increased connectivity between neurons occur
- Brain regions experience blooming and pruning
- The visual cortex exhibits peak synaptic overproduction followed by gradual retraction
- Heredity and environment influence the timing and progression of brain development
- Myelination rates vary
Physical Growth and Development in Infancy
- Newborn infants typically sleep 16-18 hours per day
- Sleep duration reduces to 14 hours per day by 4 weeks
- Night waking is the most common infant sleep-related issue
- Excessive parental involvement in sleep-related interactions is linked to night waking
- Shared sleeping practices vary across cultures
- The American Academy of Pediatrics discourages shared sleeping
- Potential benefits of shared sleeping include promoting breastfeeding and quicker response to crying
- Bed-sharing increases the risk of sleep-related deaths, including sudden infant death syndrome.
Sleep/Wake States
- Regular sleep: closed eyes and regular respiration
- Irregular sleep: closed eyes, REM sleep, limb movement, and facial grimaces
- Drowsiness: infant is falling asleep or waking up, characterized by inactivity
- Alert inactivity: infant's eyes are bright and follow moving objects
- Waking activity: infant engages in diffuse motor activity, may become fussy
- Distress: intense crying and motor activity
Motor Development
- Infants develop motor skills through perceiving and acting
- Motor skills represent solutions to goals
- Motor development is an active process involving nature and nurture
- Development follows the cephalocaudal principle
- Motor behaviour is displayed in rhythmic patterns
Gross Motor Skills
- Involve large muscle activities
- Posture is a dynamic process linked to sensory information
- Learning to walk typically occurs around the first birthday
- Infants learn about safe surfaces and places for locomotion
- Milestones vary by as much as 2-4 months
- Experience can influence the onset of motor accomplishments
- Some infants don't follow the standard motor development sequence
- By 13-18 months, toddlers can pull toys and climb stairs
- By 18-24 months, toddlers can walk quickly, balance, walk backward, stand, and kick a ball
- Restricted motor activity doesn't impact reaching motor milestones at a normal age
Fine Motor Skills
- Involve finely tuned movements such as using spoons, buttoning shirts, reaching, and grasping
- The Palmer grasp involves grasping with the whole hand
- The pincer grip involves grasping with the thumb and forefinger
Sensory and Perceptual Development
- Vision: Newborn's vision is 20/240, improving to 20/40 by 6 months
- Infants show interest in human faces soon after birth
- Infants spend more time looking at their mother's face than a stranger's face
- A 2-month-old scans more of the face than a 1-month-old
- Colour vision develops at 4-8 weeks, with colour preference at 4 months
- Perceptual constancy: sensory stimulation changes, but physical world perception remains constant
- Size constancy: recognition that an object remains the same despite changes in retinal image
- Shape constancy: recognition that an object remains the same shape despite orientation changes
- Depth perception is studied using the "visual cliff"
- Infants between 6-12 months can distinguish depth
Language Milestones in Infancy
- Biological influences: Evolution of nervous system, vocal apparatus, and language-specific brain regions like Broca's area (language production) and Wernicke's area (language comprehension).
- Language Acquisition Device (LAD) theory: Children are biologically endowed to detect language features and rules.
Emotional and Personality Development
- Emotion: Feeling or affect triggered by significant events
- Biological influences: Certain brain regions, like the limbic system and amygdala, are involved in emotions.
- Environmental influences: Relationships and culture shape emotional experiences.
- Primary emotions: present in humans and animals
- Self-conscious emotions: require self-awareness and a sense of "me"
- Fear: One of the earliest emotions in babies
- Stranger anxiety: Showed by infants as fear and wariness toward strangers, appearing around 6 months and intensifying at 9 months
- Emotional regulation and coping are influenced by caregivers, who reduce stress hormones through soothing and swaddling
- Infants gradually learn to minimize emotional reactions
- Spoiling is not possible within the first year of life
