Child Development and Growth
Growth versus development
Growth is quantitative and measurable - height, weight, head circumference. Development is qualitative and functional - skills, reasoning, social behaviour. Growth stops at maturity; development continues through life. The paper tests whether you can classify a statement correctly and apply the standard principles to a described child.
Core principles
- Cephalocaudal: control develops head to foot - head lifting precedes sitting, which precedes walking.
- Proximodistal: from the body's centre outward - shoulder control before finger control.
- Mass-to-specific: whole-arm swipes precede the pincer grasp.
- Development is continuous, sequential and cumulative, yet rates differ between children (individual differences).
- Heredity sets the possible range; environment decides where in that range a child lands.
Domains and stages
Physical-motor, cognitive, language, socio-emotional and moral domains develop together. Piaget: sensorimotor (0–2), preoperational (2–7), concrete operational (7–11), formal (11+). A nursery child of 3–5 is typically preoperational - egocentric, animistic, fooled by appearance, and learning through the senses and action rather than verbal explanation.
Worked example
"An 8-month-old lifts her head steadily but cannot pick up a raisin. Which principle explains this?" The head lift is a head-to-trunk gain; the raisin needs a pincer grasp, a fine distal skill. The gap is explained by cephalocaudal plus proximodistal direction - both patterns are normal, not delay.
Traps
Calling a milestone deviation a disability without checking the norm; treating a fall on the growth chart as slow development; saying development ends at 18; assuming all children of one age are identical.
