What developmental milestone typically occurs around 9-12 months of age?

The developmental milestone of developing a pincer grasp typically occurs around 9-12 months of age, making it an essential skill during this period. The pincer grasp involves the ability to use the thumb and forefinger to pick up small objects, which signifies an important advancement in fine motor skills. This skill not only supports further development in grasping and manipulating items but also lays the groundwork for later abilities such as self-feeding and writing.

While standing unassisted often occurs a bit later and is seen with more advanced gross motor skills, and cruising along furniture usually happens in conjunction with standing, the pincer grasp represents a critical cognitive and motor achievement during this specific age range. Climbing stairs is a skill that develops even later as it requires a combination of balance, strength, and coordination that typically emerges after the 12-month mark.
