Developmental Milestones at 1 Year (12 Months)
The 12-month mark is a critical transition point in pediatric development, characterized by the emergence of independent mobility and the start of social communication.
1. Key Domains of Development
| Domain | Milestone |
|---|---|
| Gross Motor | Stands alone, may take first independent steps, cruises furniture. |
| Fine Motor | Mature pincer grasp (thumb-index finger), releases objects voluntarily. |
| Language | Says “mama”/”dada” specifically; understands simple commands. |
| Social/Adaptive | Waves bye-bye, plays pat-a-cake, and shows stranger anxiety. |
