Infants like a pattern similar to a face the most, and also contrasting graphics like checkerboards and bullseyes. Other patterns like black and white circles, dots, squares, and stripes are also good. Babies grow and develop quickly during the first year. Stimulating infants with sights, sounds, smells, touch, and taste can increase their curiosity, attention span, memory, and nervous system development. Also, babies stimulated during infancy have better muscle coordination, weight gain and might achieve a better self image.
All babies are different, and they develop at their own rate.
They'll learn to concentrate more as they grow. The time you spend with your baby should be fun, natural, and never forced. Be sensitive to your infant's cues that he's ready to play. The best time is when she's alert and quiet. When your baby gets fussy and cries, he's tired and needs to rest.
