🧠 Developmental Milestones: 6–12 Months

🧬 Overview

Between 6 and 12 months, babies go from quiet observers to mobile, curious explorers. You’ll see big leaps in movement, communication, social interaction, and thinking. Each baby progresses at their own pace — what's most important is steady growth over time.

Development doesn’t follow a straight line — it’s full of loops, plateaus, and bursts.

đź“… Month-by-Month Highlights

  • Sits with or without support

  • Recognizes familiar faces and begins to show stranger anxiety
  • Passes objects hand-to-hand
  • Enjoys mirror reflections

✅ 8–9 Months

  • Begins crawling or scooting
  • Sits steadily without support
  • Uses pincer grasp (thumb and finger) to pick up small objects
  • Understands "no" and responds to own name

đź§© Tips for Parents
