Early Childhood Development
Early Childhood Physical Development - Lucía G. Medina, MA.
Overview
Focuses on the physical and developmental changes during early childhood, particularly toddlerhood.
Toddlerhood vs. Early Childhood
Physical Appearance:
Toddlers:
Characterized by a short and stocky appearance.
Early Childhood Kids:
Appear longer and leaner.
Early Childhood Brain Development
Key Components:
Cell Bodies: Fundamental unit of the brain responsible for processing information.
Axon: A long projection that conducts electrical impulses away from the neuron's cell body.
Synapses: Junctions between neurons that allow for communication through neurotransmitters.
Dendritic Growth: The increase in the number of dendrites that receive signals from other neurons.
Essential Functions
Inhibitory Control: A key executive function allowing children to manage impulses and emotions effectively.
Working Memory: The ability to hold and manipulate information in one's mind for short periods.
Cognitive or Mental Flexibility: The capacity to switch between thinking about different concepts or to think about multiple concepts simultaneously.
Myelination: The process of coating the axons with myelin to improve the speed of information processing.
Experiences Matter: The importance of enriching experiences for optimal brain development.
Phases of Sleep
Types of Sleep:
NREM Sleep: Non-Rapid Eye Movement sleep.
Stage 1: Light sleep.
Stage 2: Light sleep.
Stage 3: Deep sleep.
REM Sleep: Rapid Eye Movement sleep, associated with dreaming.
Sleep Patterns from Toddlerhood to Early Childhood
Sleep Requirements:
Toddlerhood (1–3 years):
Total Sleep: 11–14 hours/day.
Awake Time: 10–13 hours/day.
REM %: Approximately 25–30%.
NREM %: Approximately 70–75%.
Pattern: 1–2 naps with long nighttime sleep; sleep cycles lengthen to approximately 70–90 minutes.
Early Childhood (3–6 years):
Total Sleep: 10–13 hours/day.
Awake Time: 11–14 hours/day.
REM %: Approximately 20–25%.
NREM %: Approximately 75–80%.
Pattern: Naps fade around 5 years; stable long sleep cycles (~90 minutes).
Healthy Lifestyle
Nutrition Guidelines:
Aim for 5+ servings of fruits and vegetables each day.
Limit screen time to 2 hours or less daily.
Engage in physical activity for at least 1 hour daily.
Ensure consumption of 0 sugar-sweetened drinks.
Daily Nutrition Schedule
Example Schedule:
07:00 AM: Breakfast (consistent daily).
10:00 AM: AM Snack (consistent daily).
01:00 PM: Lunch (consistent daily).
04:00 PM: PM Snack (variable).
07:00 PM: Dinner (consistent daily).
10:00 PM: Bedtime snack (variable).
Importance of predictable schedules, nutrition knowledge, modeling healthy eating, and providing pleasant mealtimes.
Childhood Obesity
Definitions:
Overweight: BMI between the 95th and 97th percentile for age and sex.
Obese: BMI above the 97th percentile for age and sex.
Statistics:
1980: ~5% of 5-year-old children were considered obese.
2021: ~15% of 5-year-old children were considered obese.
Government Actions for Promoting Healthy Lifestyles
Discussion on the roles governments can play in fostering healthy lifestyles for young children.
Nutrition Policies in Schools
Changes Under New Nutrition Standards:
Less unhealthy fat and salt in school meals.
Fewer calories and emphasis on low and non-fat dairy options.
Double servings of fruits and vegetables offered.
Increased focus on whole grains in meals.
Play and Physical Activity Initiatives
Importance of promoting walking or biking to school and ensuring safe routes for children.
Parenting Support Strategies
Emphasis on parental modeling: Children are more likely to eat fruits and vegetables if parents do the same.
Reference to the Steps to Health Program Education (SNAP-Ed) for providing education on these topics.
Importance of health screenings and affordable health services for children.
Developmental Areas in Early Childhood
Key Areas of Development:
Physical well-being and motor development.
Socioemotional development.
Cognitive development.
Language and communication skills.
Preparing children for school readiness.
Early Childhood Education Approaches
Head Start Program:
Serves children from low-income families (ages 0–5).
Emphasizes early learning standards in literacy, numeracy, and socioemotional skills.
Highlights the role of health, nutrition, and parent involvement in child development.
Quality varies across programs.
Notable Educational Approaches
Montessori Approach:
Child-led learning focusing on independence and sensory exploration.
Encourages autonomy and concentration through practical life activities.
Hands-on, individualized learning environment.
Reggio Emilia Approach:
Learning through exploration, projects, and artistic expression.
Encourages creativity and collaboration, with active parent and community involvement.
Features less structured academic focus.
HighScope Approach:
Utilizes a daily plan-do-review sequence.
Focuses on language, math, social-emotional, and motor development.
Bases its approach on strong evidence of effectiveness.
Waldorf Approach:
Emphasizes whole-child development, creativity, and connection to nature.
Focus on play and movement with limited technology use.
Considerations for Effectiveness
Factors influencing the efficacy of early childhood education include:
Child’s needs and temperament.
Family values and expectations.
Community context and support systems.
Quality of the educational program.
No single approach is deemed universally best for all contexts.
Long-term Benefits of Various Educational Approaches
Evidence of Benefits:
Head Start and HighScope: Long-term benefits associated with alleviating poverty.
Montessori: Fosters independence, executive function, and literacy gains.
Reggio Emilia: Promotes creativity, collaboration, and problem-solving skills.
Waldorf: Enriches imagination, holistic development, and commitment to environmental consciousness.
