At approximately what age do infants start to crawl?

Infants typically begin to crawl around eight months of age, which is a common milestone in their motor development. At this stage, they have usually developed sufficient muscle strength and coordination to lift their bodies off the ground and move forward using their hands and knees. This crawling phase is crucial as it enhances their spatial awareness and helps in developing balance and coordination skills that will be vital for later stages of mobility.

While some infants may start crawling as early as six months or may not crawl until closer to ten months, eight months is recognized as the average age for this skill to emerge. Factors such as individual development rates, encouragement from caregivers, and opportunities for tummy time can also influence the timing of crawling.
