The vision will change during babies' different period. 5 to 8 months, around the fifth month, depth perception begins to develop, making the ability to grab your earrings or hair that much easier. Your baby's ability to tell the difference between shades of  color is developed by 5 months. By 8 months, it's almost as good as an adult's.

Crawling at this age should be encouraged because it helps with coordination of the eyes with hands, feet and body. 9 - 12 months, during this period, your baby should be able to use his eyes and hands together well.

If your child is an early walker, you may find that hand-eye coordination actually takes longer to develop. An important reason not to rush your child into taking his first steps! Your baby should also be able to judge distances fairly well at this point and have pretty good aim when throwing things.
