A Study in Contrasts
Ever wonder why many toys for young babies come in black and white? It's because infants have an easier time distinguishing highly contrasting colors (dark shades next to light ones) than pastels.
This inclination is also why your baby, in his early weeks, often seems more interested in looking at the top of your head than in your eyes. "He's visually attracted to areas of high contrast, such as where the hairline meets the forehead," Dr. Day explains.
By 2 months, your child will start gazing more directly at you and become interested in primary colors. Point out brightly colored objects -- your yellow T-shirt, a green ball. Since your little one can now distinguish more detailed shapes and designs, it's a good time to hang that polka-dot butterfly mobile you received at your baby shower.
Now in 3-D!
Between 3 and 6 months, your baby will begin to see objects in three dimensions and acquire depth perception. Since her hand-eye coordination is developing at the same time, she may reach for things in front of her -- first by chance, then deliberately. (Watch out for those earrings!)
Your child may now notice things or people moving from clear across the room. She can also make out small objects closer to her, like blocks, and may be able to track and grasp them.
