At what developmental stage do infants commonly exhibit the ability to climb?

Infants commonly begin to exhibit the ability to climb around the developmental stage of 10 to 11 months. During this period, they are typically mastering gross motor skills, such as pulling themselves up to a standing position and beginning to crawl with more confidence. Climbing, which requires a combination of strength, coordination, and confidence in their mobility, often emerges as they explore their environment and seek to reach out for objects or climb onto furniture.

By the time infants reach 10 to 11 months, they tend to have better control of their movements, allowing them to navigate obstacles more effectively. This developmental milestone aligns with their growing curiosity and desire for exploration, which often results in climbing behaviors. At earlier stages like 6-7 months and 8-9 months, infants may also be active but are generally still developing foundational skills like sitting and crawling rather than attempting to climb. By 12-15 months, while climbing continues to develop, many infants will be more advanced and capable of climbing off or onto surfaces due to increased physical strength and coordination. Therefore, the answer corresponds with typical development patterns observed in infants around that age.
