What kind of toys would be good to stimulate my baby's sight?

You can use various visually stimulating baby toys with high-contrst colors including black and white, various textures and soft rattles or sounds,Drive and Drool Keys ,Mix'n Match Blocks etc to stimulate your baby's eyesight.

From the time your baby is born, his vision is maturing and developing. His vision is only partially developed at birth. He can see, but what he sees is not as clear or complete as an adult’s vision. His retina, which helps distinguish color and light, is not fully developed. This is why you might have heard that newborn babies see in black and white. As your baby grows and matures so do the cells in his brain that are responsible for vision. Encouraging your baby to use his vision will help in vision development and will help stimulate visual part of his brain to thrive. Some time during the first few months of life your baby will begin to track objects with his eyes. You should consult your doctor if he is not tracking by the time he is three months old.

You can do  some visually stimulating activities with your baby to help improve his vision and encourage visual maturity. Like you can encourage playing with  bright colored rattles or toys, mirrors & reflections

Also you can play peekaboo or hide and seek with your baby . You can play by covering your face with your hands and then saying “peekaboo” or once your child gets older you can cover a toy with a blanket and see if your baby can find it.

hope this helps you...

happy parenting :)
