Question

Quizplus · Accepted Answer

The ulnar grasp is when a baby uses their whole hand to grasp an object, and is common around three months of age. The pincer grasp involves using the thumb and forefinger, and typically develops around eight to ten months. Gross-motor skills refer to larger movements involving the whole body, whereas shaking a rattle is a fine-motor skill. Prereaching is when a baby makes swiping motions towards an object, but does not grasp it yet.
