What developmental milestone occurs around 6-7 months?

At around 6-7 months of age, a significant developmental milestone is the ability for infants to sit alone without support. This skill represents a major advancement in their physical development, as it indicates improved balance, core strength, and coordination. Sitting independently allows infants to engage with their environment more effectively, enhancing their ability to explore and interact with objects and caregivers, which is crucial for cognitive and social development.

Sitting without support also typically follows considerable practice in developing trunk stability, which emerges after earlier milestones such as rolling and pushing up into a seated position. This milestone is a foundational skill that supports future development in gross motor skills, including crawling and eventually standing and walking. Understanding this timing helps caregivers and educators recognize typical patterns of growth and identify potential delays.
