Final answer:
The pincer grasp typically develops in infants around ten months of age, when they gain the ability to grab objects with their thumb and forefinger.
Step-by-step explanation:
The development of the pincer grasp in infants normally occurs around ten months of age. This skill allows an infant to pick up objects using the tips of the thumb and forefinger.
By ten months, infants not only develop the ability to use a pincer grasp, but they also learn to crawl, sit unsupported, search for dropped objects, and start to babble in a way that imitates the cadences of speech.
