Human Development: Stages of Growth and Child Care
What this domain tests
This domain tests the stages of development, the principles governing growth, and practical child-care – feeding, immunization, weaning and adolescent health.
Growth versus development
Growth is a measurable increase in size or weight - quantitative. Development is progressive change in skill and function - qualitative. Both continue from conception to death.
Principles of development
It is continuous, sequential, follows cephalocaudal (head to toe) and proximodistal (centre outward) directions, proceeds from general to specific, and shows individual differences in rate.
Stages
Prenatal; infancy (0–2 years); early childhood (2–6); later childhood (6–12); adolescence (12–19); adulthood; old age.
Child care essentials
Exclusive breastfeeding for the first six months including colostrum; complementary feeding from six months; immunization as per the Universal Immunization Programme - BCG and OPV at birth, pentavalent doses in the first months, measles-rubella at 9–12 months; safe play, toilet training, and adolescent hygiene including menstrual hygiene.
Worked example
A nine-month-old is still solely breastfed and has not gained weight. Reasoning: breast milk alone cannot meet energy and iron needs after six months. Advice: start soft mashed complementary foods - dal-rice, khichdi, mashed banana, curd - along with continued breastfeeding.
Traps that cost marks
- Using growth and development as synonyms.
- Reversing cephalocaudal and proximodistal.
- Saying weaning means stopping breast milk; it means adding complementary foods.
- Skipping colostrum as 'impure' - it carries protective antibodies.
