Which developmental milestone is typically seen in a 9-month-old?

1. Pincher grasp

2. Walking

3. Speaking intelligible words

4. Sitting up without support

The correct answer is: Pincher grasp

The pincher grasp is a fine motor skill that typically emerges around 9 months of age. At this stage, infants start to develop greater dexterity and control over their finger movements, allowing them to pick up small objects using their thumb and forefinger. This skill is crucial for various self-feeding activities and manipulation of toys, marking an important aspect of their gross and fine motor development. Sitting up without support is generally achieved earlier, around 6 to 8 months, indicating that while it is an important milestone, it is not specific to the 9-month mark. Speaking intelligible words typically begins closer to the first year of life, as children start to form recognizable sounds and words. Walking usually occurs around 12 months or later as children continue to strengthen their muscles and coordination. Thus, the pincher grasp is the most characteristic milestone to expect at 9 months of age.
