Winder's Stage 2 is associated with which age range?

• A. 0-6 months
• B. 6-18 months
• C. 18-30 months
• D. 24-36 months

Answer: (B)

Winder's staging describes developmental phases by age, with the second stage lining up with the period when infants move from mostly reflexive behavior to purposeful movement and exploration. This is the time around six to eighteen months, when babies begin to sit independently, crawl or begin to pull up, and show early object exploration and first words or babbling. The cluster of skills and changes during this window fits best with the six-to- eighteen-month range, distinguishing it from the earlier newborn/reflexive period (0–6 months) and the later toddler period (18–30 months or 24–36 months) where walking is established and language and complex play are more advanced.
