Which milestone appears earlier: social smile or pincer grasp?

Explanation:
Social responses appear before fine motor precision. A social smile typically shows up around 6 to 8 weeks (often by about 2 months) as the infant begins to engage with caregivers and respond to faces. The pincer grasp, which uses the thumb and index finger to pick up small objects, develops much later, roughly around 9 to 12 months as hand muscles and coordination mature. So, the earlier milestone is the social smile because social engagement emerges early in infancy, while precise finger control for a pincer grasp comes later in the first year.
