SHARE WITH FRIENDS:

Medically young children are classified by different names. That is,

• A baby is a child under one year of age;
• Baby - from birth to four weeks;

In addition, according to the duration of development in the mother's womb,

• Menstrual babies are babies born at 38-42 weeks of gestation;
• Premature babies are children born between 28-38 days of gestation;
• Underdeveloped children are premature babies who are not adapted to living outside the mother's body. In addition, the fetus may not develop well under the influence of various factors (tobacco, alcohol, drugs, sexually transmitted diseases, infectious diseases, uncomfortable external environment, various chemicals).
• Premature babies are babies born after 42 weeks of gestation with specific symptoms, stiffness of the skull, skin rash, central nervous system deficiency.

After birth, the child's body undergoes significant changes. For example, the flow of oxygen and nutrients from the mother's body stops. With the first scream, the lungs begin to function, and the baby begins to breathe independently. Blood circulation and metabolism change. During infancy, all organs adapt to the external environment, are formed, and adaptation ends by the end of the period. Now the process of formation and growth in the child is accelerated. That is, the child develops physically and mentally, the functions of all organs improve.

Baby weight and height

The average weight of a full-term baby is 3200-3500 grams, and his height is 49-53 cm. A premature baby usually weighs 2550 g and is 47 cm tall. A premature baby weighs more than 4000 grams and does not grow tall. In the first, 3-4 days of the baby's life, the weight is reduced by 100-300 grams. That is, normal physiological weight loss occurs. At this time, the baby’s mother or family members don’t have to worry. However, if the weight is too low, the baby should be taken to a pediatrician immediately. By the end of the second week, the baby will reach its birth weight. Now let's sort the growth and weight gain of a child under one year of age:

• By the end of the first month, the baby weighs 700-800 grams;
• By 4-5 months, children gain 2 times their weight;
• By the end of the year, by the age of one, he weighs 10 pounds.

 

• In the first, 3 months, the child grows every month from 2.8-3 cm in height;
• Grows from 4 cm in 6-2,5 months;
• Grows around 7-9 cm at 1,5-2 months;
• In 10–12 months it exceeds 1 cm.

On average, in the first year of life, the body length increases to 25 cm, and by the end of the year it reaches 75 cm. The annual growth rate of a premature baby is 25-44 cm, and at the age of one year the child is 68-73 cm.
