Which of the following would indicate a potential fine motor issue in a child under 18 months?

Using only fist movement in a child under 18 months can indicate a potential fine motor issue because it suggests limited dexterity and control over hand movements. At this developmental stage, children are expected to start demonstrating more sophisticated hand function, such as the ability to manipulate objects with their fingertips and engage in a variety of grasp patterns.

By this age, typically developing children begin to exhibit a pincer grasp, where they use their thumb and forefinger to pick up small objects, reflecting an important milestone in fine motor development. When a child relies solely on fist movements, it may indicate that they are not progressing appropriately in their fine motor skills, which are critical for tasks like feeding themselves, stacking blocks, or engaging in creative play.

In contrast, other options like playing with one finger or holding objects with both hands represent normal variations of motor skills that don’t necessarily signal a developmental delay. Pushing toys with both hands is also common and reflects appropriate motor development by demonstrating coordination. Therefore, the reliance on fist movements is a key indicator of potential concern in the development of fine motor skills.
