What is a key developmental milestone for a child at 6 months?

A key developmental milestone for a child at 6 months is the ability to sit with support. At this age, infants typically develop the core strength and balance necessary to sit upright with some support, such as leaning against a caregiver or a firm surface. This skill marks an important stage in physical development, as it allows children to explore their environment more effectively and engage in activities that promote further development, such as reaching for toys.

At 6 months, most infants are not yet capable of crawling independently; this typically occurs closer to 8-10 months. Walking unaided is usually achieved around 12 months or later, and speaking simple sentences does not emerge until about 18-24 months. Therefore, sitting with support is a significant and expected milestone at the 6-month mark that reflects growth in both physical strength and coordination.
