Immediately after the birth of a newborn baby is totally dependent on the mother. He is constantly talking to her, and gradually both begin to understand each other just by facial expression, for facial expressions and smiles. That is why children who are brought up without a mother, begin to fall behind in the development of their peers.
Why depend mimicry newborn baby
All children are born with the same symmetrical facial expressions. A newborn baby can open and close his eyes, much zazhmurivat them, frowning and raising eyebrows, opened her mouth, pulling her lips proboscis, making sucking movements and even "smile" (smile in newborns usually reflects their comfortable inner state). Nasolabial folds of the child at a voltage of language become more pronounced. A newborn baby can for some time (for each child this time can be different) to fix the eye. His face had a full-term newborn baby mostly calm, but some discomfort, it can become distracting. Dissatisfied, anxious expression can be a newborn for various violations of the internal organs and systems.
Mimicry of a newborn baby due to reflexes, called primitive physiological or due to immaturity in the brain. With the maturation of the brain and spinal cord, these reflexes fade, giving way to a conscious mimicry.
In the development of the child's facial expression may be noted two related trends: the increasing complexity of conscious mimicry and the extinction of a number of congenital unconditioned reflexes. By the nature and rate of extinction of unconditioned reflexes can judge the correctness of the neuropsychological development of the child.
Recently I conducted a lot of research mimicry newborn children. It revealed that in some cases the facial expression of a newborn baby is dependent not only on innate reflexes, but also from external influences. After the first days of the baby responds to the mother calms down when she speaks to him softly and picks up.
Main unconditioned reflexes of the newborn, reflecting on his facial expressions
Mimicry newborn depends mainly on unconditioned reflexes, provide the brain, it is called oral segmental automatisms that allow sucking and appear on the first day of life.
Sucking reflex - Sucking the breast, nipple or thumb that irritate the mouth. This reflex is preserved for a long time, throughout the period of breast development.
Proboscis reflex - contraction of the circular muscles of the mouth with gentle effleurage finger on the lips of the child, causing his lips stretched into a proboscis. Proboscis reflex normally lasts up to 3 months. If it lasts longer, it says about some changes in the brain.
Search or ingratiatingly reflex Kussmaul - a light touch of your fingers to the skin at the corner of the mouth causes the corner of his mouth down and simultaneously turn their heads toward the irritation. This reflex is especially pronounced when the baby is hungry. It holds up to four months of age and then gradually replaced by visual stimuli in the form of preparation for the next mother breast feeding.
Hand-roto-head reflex (a reflex Babkin) - when pressed with your finger baby hand, it opens the mouth and simultaneously bends the head to the chest. This reflex is also more pronounced before feeding. If this reflex is expressed in the first days of life, it is a good prognostic sign for children born with a birth injury
Birth injuries - than they threaten your child?
. In the first 2 months Babkin reflex is significantly, but then begins to subside 3-4 months it takes.
At various lesions of the central nervous system in the newborn can notice the asymmetry of the face. On the first day it can be a consequence of the passage of the baby's head through the birth canal, but if it lasts longer, it may speak of some neurological disorders. Thus, the asymmetry of the mouth when the baby crying and yawning may be a sign of the defeat of the trigeminal nerve

Development of the facial expressions of the child in the first month of life
If in the first days of life, all the movements of the child, including his facial expressions, reflex, then a few days later the child begins to do some conscious movement. For example, turn his head to light react to loud noises startle emote

If the mother noticed some peculiarities in the behavior of the child, who seemed suspicious to her, she should be sure to inform the pediatrician (in the first month of life the pediatrician visits the child at home on a weekly basis). This is very important because early detection and treatment of any violations, can prevent a variety of diseases in children after a year, and even in adults.
