Which sequence best represents the standard motor development progression in infancy?

• A. Reach & miss, sit alone, creep, climb stairs, stand alone
• B. creep, sit alone, climb stairs, stand alone, reach & miss
• C. creep, sit alone, climb stairs, reach and miss, stand alone
• D. sit alone, creep, climb stairs, reach and miss, stand alone

Answer: (A)

The main idea is that infant motor development typically follows a path from early arm control toward increasing postural stability and then toward independent mobility. Early intentional arm movements, like reaching for objects, appear first as the infant gains basic hand-eye coordination. Sitting alone reflects enough trunk and hip control to support the body without external support, a prerequisite for more elaborate movement. Once the infant can sit with stability, crawling or creeping emerges as the first form of self-initiated locomotion, using coordinated arm and leg movements to move around. After gaining experience with upright lower-body use and balance, the child may begin more challenging tasks such as climbing stairs, which require coordination and leg strength, and finally achieve standing independently, marking a transition toward walking. This sequence emphasizes a stepwise increase in independence and motor control, aligning with typical developmental milestones observed in infancy.
