Once the infant is born, my mom and dad, grandparents, uncles and aunts, and other relatives, the question arises - to whom it seems a little miracle?Mom begins to look into the tiny face still in the hospital, trying to catch his dad looking at the features of the baby through the window of the hospital.But do not forget that after the birth of his child does not always look the way that parents wanted and expected.It will take some time to get the baby adapt to the environment and took a normal appearance.
Usually the child immediately after birth may be: irregular-shaped head, with some deformation;long body and bulging tummy;chest may appear swollen and she can be released from the liquid, both girls and boys - all of these changes are normal for the newly born human and tested in a few days.Also initially be snub or slightly beveled tip to one side, which will take its normal shape after some time, and only in the final period of puberty.Of particular interest are the eyes of the newborn - baby often is born blue-eyed.Why is this happening?
The structure and the structure is similar to a newborn glazik eye of an adult.It is a kind of camera, in a system that includes the optic nerve, is a conductor of information to the brain - namely, at a portion thereof able to perceive and analyze seen.The structure of the eye is divided into "lens" - the lens and cornea, and "film" - which is sensitive retina shell.
Although eye baby and is identical to the eye of an adult, fully operational, he still can not.Visual acuity of the newborn is very low, it can be compared to the feeling of light, no more.With the development of the newborn visual acuity increases, and by the age of one year reaches 1/2 of the norm of an adult.So in the first week of life the child's vision checked the reaction of the pupil to light.In the second week of fixing should take place on the subject for a few seconds.By the second month of life becomes stable fixation.By 6 months, the child already differentiates between simple shapes and a year - various patterns.
Eye color depends on the melanin - the so-called iris pigment.A child is born with light blue eyes and only two or three years he changed the color of the eye finally, at this time there is a pigment called melanin.In consequence of that, bright eyes of a child may eventually become green, gray and brown.Accordingly, the darker the eye color, the more melanin is accumulated.The amount of melanin due to heredity.According to the results of studies in the world more than brown-eyed people than light-eyed, the cause is genetic dominance symptoms that are associated with a lot of melanin.Thus, if one of the parents, dark eyes, and the second light - the probability that a newborn baby will eventually brown eyes.
light-eyed people are exposed to fluctuations in the color of the eyes, it can vary depending on the colors of the clothes and the environment.They are also subject to change eye color in stressful situations and during a disease.For some, the color of the eyes of the parents of the child will be very important for someone will not play a significant role.After all, in fact, the main thing is that the baby grow up healthy and really happy!
