From 6 to 9 months, which grip uses the side of the thumb and first fingers?

• A. Superior pincer grip
• B. Inferior pincer grip
• C. Self feeding
• D. Grasping

Answer: (B)

The main concept here is how infants develop finer hand control and precision grips during the first year. Between six and nine months, babies begin to use a grip that involves the side of the thumb pressed against the first fingers to pinch and pick up small objects. This is the inferior pincer grip, a sign of growing finger strength and coordination.

This grip sits between earlier, broader grasps and the more precise tip-to-tip pinch that comes a bit later. The other options describe broader activities or later-stage skills (a different, more precise pinch; self-feeding as a whole; or grasping in general), so they don’t match the specific 6–9 month fine-motor pattern.
