Six to Eight Months
Most babies start crawling by 6-8 months, further developing eye-body coordination. They judge distances and set visual goals, seeing something and moving to get it. This sudden freedom allows for new experiences and the rapid development of visual perception skills as babies experience their own bodies in relation to other objects and notice differences in size, shape, and position. By the 6th month, babies acquire fairly accurate eye movement control. Some experts caution that early walkers may not learn to use their eyes together as well as babies who have crawled a lot and teamed their eyes more when looking at objects up close.
