Question: 1 / 400

Which milestone would be considered the most advanced for a 6-month-old?

Reaching for objects

Rolling over from back to front

Laughing out loud

Sitting unsupported for short periods

Sitting unsupported for short periods is considered the most advanced milestone for a 6-month-old infant. This skill indicates significant strength and coordination development in the muscles necessary for maintaining balance and posture independently, which usually occurs between 6 to 9 months of age.

While reaching for objects, rolling over from back to front, and laughing out loud are all typical milestones reached around the same age, they generally indicate earlier stages of motor and social development. Reaching for objects shows hand-eye coordination and desire to interact with the environment, rolling over demonstrates gross motor skill development, and laughing out loud reflects social and emotional growth. However, sitting unsupported is a more complex task that requires greater muscle control, balance, and coordination, making it a key indicator of advanced physical development by 6 months.
