Stage 4 of Winder's development is characterized by crawling, creeping, quadruped mobility, and transitions from standing to sitting. Which stage does this describe?

• A. Stage 3
• B. Stage 4
• C. Stage 5
• D. Stage 2

Answer: (B)

In this stage of Winder’s motor development, the child moves from lying and basic upright transitions to more advanced mobility that uses a hands-and-knees position and the ability to shift between different postures. Crawling and creeping indicate the emergence of quadruped mobility, where the arms and legs work together to propel the body, and transitioning from standing to sitting shows developing balance and weight-shifting control to move between upright and seated positions. These capabilities come after simpler rolling and sitting, but before independent walking, so they fit squarely in Stage 4.
