The physical development of a small child during the first six months of life
jpg width = 500 “height = 350” / gt; Every child loving his child worries about whether everything is good for his baby? Is it developing correctly? Does the child have any problems? In order not to feel unnecessary anxiety and anxiety, you need to closely monitor the baby in the process of its growth, at each stage of its development. In the first year of life, children grow and learn with incredible speed. And help in monitoring these parents can provide a directory of child development, which was developed by specialists. In it for months are painted all the skills and abilities that your kid should master at a certain age. And if you give your child everything he needs and provides him with a happy childhood, he will equally remarkably develop in all directions:
- physical (the rate of increase in height and weight),
- cognitive (ability to learn and memorize),
- social (the emergence of reaction to the surrounding world and native people),
- motor (improving motor skills and skills),
- development of speech (language training).
Physical development of a child up to a year depends both on hereditary factors, and on the influence of the environment and social conditions. There are two groups of causes that affect birth, growth, weight, and other parameters after birth: endogenous and exogenous.
The endogenous factors include the endocrine glands and the effect they have on the child. Initially, during the newborn period, an important role is played by the thymus gland, from the second year of life the thyroid hormones play an important role, and from the age of 3-4 years on, the pituitary gland subsequently exerts its influence. The genotype determines the level of hormones from these organs and the sensitivity of tissues to their effects.
Regardless of growth, and from all other criteria, body weight is the most unstable indicator, which can change quite quickly under the influence of various causes (a child's illness, an eating disorder, a sleep disorder). A small set of body weight may be due to malnutrition, poor care (lack of outdoor walks), frequent illnesses of the baby. With excess weight, which is more often from overfeeding, children suffer from the weakness of immunity, are more prone to cardiovascular pathologies, diabetes.
The most intensive weight gain occurs in the first 3 months of life. A full-term newborn has an average weight of 3-3.5 kg. With the normal course of the adaptation period, most children have a physiological weight loss of up to 10% of birth weight by the fifth day of life, which is restored to normal within a few days. The maximum increase in body weight is noted in the first six months (hereinafter its rate is decreasing) and is: in the 1st month of life of the child - 600 grams, in the second - 800, in the third - 750, in the 4th - 700, in 5th - 650, in the 6th - 600 gr. On average, by 4.5 months the body weight is doubled.
However, the dynamics of the increase can vary greatly and depend on many external factors and characteristics of the child. For example, children who are on artificial feeding, a month later, double the weight than those who are nurtured naturally. Therefore, unlike growth (which is a more stable indicator and does not change immediately under the influence of different conditions), the weight of the child shows the current state of the organism. Pathology does not consider the deviation of the mass from the supposed less than 10%.
