Which stage includes rolling and related early mobility milestones in Winder's model?

• A. Stage 1
• B. Stage 3
• C. Stage 4
• D. Stage 2

Answer: (D)

Rolling represents the shift from reflexive, pattern-driven movement to purposeful, coordinated mobility. In this stage, infants begin to explore movement through basic transitions and weight shifting, with rolling from prone to supine (and later to the side) as a key milestone that shows emerging trunk control and rotational ability.

Within this framework, Stage 2 is the period where early mobility tasks like rolling and related weight-shift actions appear, serving as a bridge to more complex skills such as sitting and subsequent crawling. It marks the move from mostly reflexive movement to intentional movement that allows the infant to explore their environment.

Earlier stages focus more on reflexive and foundational patterns, while later stages advance toward more upright postures and independent locomotion. Therefore, rolling and these early mobility milestones fit Stage 2 best.
