At what age does an infant typically begin to crawl?

Infants typically begin to crawl between 8 to 9 months of age. This developmental milestone is an important part of physical growth as it indicates increased muscle strength, coordination, and spatial awareness. By this age, most babies have developed the necessary trunk and limb strength to support themselves while moving on their hands and knees. Crawling also serves as a precursor to more advanced motor skills, such as standing and walking.

While some infants may start crawling a bit earlier at 6 to 7 months or even as late as 10 to 11 months, the widely accepted range for the onset of crawling is generally around 8 to 9 months. Therefore, the answer accurately reflects the typical developmental timeline for this activity in infants.
