Which developmental milestone is expected around 18 months?

At around 18 months of age, one of the key developmental milestones is the ability to walk independently, also referred to as "walking alone." This is a significant achievement in gross motor development and typically occurs between 12 and 18 months. Walking unaided demonstrates a child's improved balance, coordination, and strength.

At this age, children are also refining their walking skills, which may include changing direction and walking on different surfaces. The ability to walk independently is crucial as it allows children to explore their environment further, which helps in developing other skills and enhancing their social interactions.

Assembling a 3-block tower, walking with support, and balancing on one foot are milestones that are generally expected either before or after 18 months. Assembling a tower usually happens around age 2, walking with support typically occurs earlier, and balancing on one foot is usually seen closer to age 3 or older. Thus, independent walking is uniquely characteristic of the 18-month milestone.
