What are primitive reflex newborn

Normal newborns born with a certain innate reflex. The reflection can reflect the soundness of your baby's body, the nervous system is functioning.

Some of these early abnormalities can also be seen in reflection of the changes. If you put thumb pressure in the newborn at the same time on both sides of hands, his mouth will open, and forward bow, with eyes closed action, is called Baba eating, this reflection has occurred after birth, 6 weeks after will gradually weaken, if 4 months after birth, continued to exist, that there are brain lesions.

When you face with your fingers touch the newborn, he will turn to touch this side and open his mouth.

Quiet wakefulness in newborns, the mother newborn in her arms, touching his left cheek to his mother newborn nipples, this reflection will lead to the first baby turns his head toward the left and open on the lower lip, and then find and bite live nipple started sucking.

This reflex occurs after students called primitive reflex (also known as neonatal transient reflection), this type of reflection is unique to newborns after birth skills. With increasing age, the gradual development of the central nervous system, these reflections will be gradually weakened and vanished. Most of reflection if 3-4 months after birth, continues to exist, the brain lesions suggestive of some reflection, such as cervical limb reflex will disappear after 6 months.

Some scholars believe that the grasp reflex represents an evolutionary adaptation. Newborns have the ability is to "protect" themselves.

In some cases, your baby can even support its own weight and help the drop-down to the seat.
