At what age do infants typically begin to sit with help or support?

Infants typically begin to sit with help or support between 4 to 6 months of age. This developmental milestone is an important part of a child's motor skills progression. During this period, babies develop the muscle strength and coordination needed to maintain an upright position when given some assistance, such as being propped up by pillows or held by a caregiver.

At around 4 months, infants are gaining control over their neck and back muscles, which allows them to stabilize their bodies when placed in a supported sitting position. By 6 months, many can sit for extended periods while relying on their hands for balance. This stage sets the foundation for further motor developments, including sitting independently, crawling, and eventually walking.

As infant growth and development timelines can vary, some children may reach this milestone slightly earlier or later, but the 4 to 6 month range is widely recognized in pediatric developmental assessments.
