Sensory and Motor Growth in Newborns - Topic Overview
Your newborn is equipped with all
five senses, although some are more developed than others.
- Touch. Your newborn's
sense of touch is highly developed, particularly around the mouth, where he or
she is sensitive to temperature, pressure, and pain. Newborns like gentle
handling and to feel soft textures against their skin.
- Hearing. At birth, fluid in the ear canal and middle ear may
affect your baby's hearing. This fluid usually clears in a few days, and after
that your newborn can hear fairly well. Babies are especially responsive to
high-pitched and loud sounds. Your newborn baby also recognizes and prefers the
- Smell. Like touch, your
newborn has a well-developed sense of smell. Your baby is also tuned into the
smell of the mother and can recognize her scent within the first few days of
life. Newborns like sweet smells.
Newborns prefer sweet tastes; they generally avoid sour, bitter, and salty
- Sight. Newborns' vision and their
responses to what they see develop rapidly during the first year. Your newborn
sees best out of the corner of his or her eyes (peripheral vision) and when
objects are about 9 in. (23 cm)
to 12 in. (30.5 cm) away.
Newborns can see color, but are most attracted to bold and contrasting
patterns. By 3 months of age, infants can look directly at and follow objects.
Around this time they are also particularly attracted to the human face. Don't
be alarmed if your baby's eyes wander or cross periodically during the first
month—this is normal. Children with normal vision usually develop 20/20 or
20/40 eyesight by 3 years of age.
Newborn motor skills
develop as your baby's muscles and nerves work together.
prompt your newborn's limb movements. Reflexes are involuntary movements made
when another part of the body is stimulated. For example, when the side of a
newborn's cheek is touched, the baby turns his or her head in that direction,
opens his or her mouth, and tries to suck. This is called the rooting reflex.
Newborn reflexes disappear in the first months of life as the brain matures.
