What is the correct sequence of cephalocaudal milestones as described in the material?

• A. Lift head when prone; Sit unsupported; Gain complete head control; Crawl; Walk
• B. Lift head when prone; Gain complete head control; Sit unsupported; Crawl; Walk
• C. Lift head when prone; Crawl; Sit unsupported; Gain complete head control; Walk
• D. Crawl; Lift head when prone; Sit unsupported; Gain complete head control; Walk

Answer: (B)

Motor development proceeds from head to toe. The infant first gains control of the head and neck, then develops trunk stability, and only after that moves to unsupported sitting and later to mobility on the floor and on foot. The earliest milestone is lifting the head when placed on the abdomen. After that, full head control is established, providing the foundation for sitting. Once sitting unsupported is achieved, crawling emerges, followed by walking. Therefore the sequence is: lift head when prone → gain complete head control → sit unsupported → crawl → walk. Reasoning for the other orders: sitting before full head control would require stability the infant hasn’t yet developed; crawling before head and trunk control would skip the natural top-to-bottom progression.
