The majority of infant crib toys are produced in pastel shades such as light blue or pink. Based on research on the visual abilities of newborns, have the class discuss the colors and designs for toys that would stimulate the infant visual system. in

The correct answer is Central Nervous System

When we think of colors for baby's accessories, bedroom or clothes, we almost always think of soft, pastel colors. However, and especially in the first year of life, the baby is mainly attracted by high contrast color schemes.

When the baby is born, the eye and structures that connect it to visual centers in the brain are not yet fully developed. This means that babies' initial vision is not as sharp as that of an adult.

Newborns see objects about 30cm apart (approximately the distance between the mother's face and the baby's face when breastfeeding) and cannot distinguish certain shades of color very close together such as orange or shades pastry.

As vision develops, babies are attracted to high-contrast color schemes (black and white or black and primary colors), at an early stage by the black and white scheme.

A puppet recommended for any baby at this stage is a panda, but there are also books with more or less complex high-contrast patterns that can be used to stimulate the baby's curiosity and senses, such as disks, nannies, activity mat (which promotes motor development, it is excellent for the development of the digestive system and to prevent colic in the baby, but it is also a precursor to crawling and walking), puppets for the feet (which can be placed on the baby's foot during molting a diaper and that stimulates the baby to reach the foot to grab it) or other toys.

The important thing to remember is that, through small gestures integrated into the daily routines of the newborn and baby, their neurological development is promoted.
