At what age does a child typically reach the developmental milestone of rolling over?

The developmental milestone of rolling over is typically reached around 6 months of age. At this stage in their growth, infants generally have developed sufficient muscle strength and coordination to roll from their stomachs to their backs and vice versa. This milestone is significant as it reflects the child's developing motor skills and overall physical development.

Prior to 6 months, many infants are still in the process of gaining the necessary control over their bodies to achieve this movement. Rolling over is an important precursor to further milestones in mobility, such as sitting up and crawling, which usually occur as they continue to gain strength and coordination. Consequently, reaching this milestone at around 6 months is a standard expectation in child development.
