You have waited so long for the birth of the baby. In dreams, you saw what it is, how it grows and develops. When a child is finally born, young mothers are faced with questions that concern the development of the baby. One of them is the norm of weight in children under one year. The table and average indicators established by specialists will help you to understand this.
Weight at birth
The newborn must be examined by a pediatrician. At the first examination your baby is weighed. After the necessary number of days spent in the hospital, the child is weighed again. It is these numerical data-weight at birth and weight on the day of discharge-that affect the further increase in weight.
All children have their own individual characteristics at birth. The normal weight of a healthy baby is from 2700 to 3700 g. It should be noted that the initial weight of your child depends on such factors as:
- Health of the baby.
- Heredity. For larger moms, babies with greater weight are more often born than in thin and short women.
- Paul. Basically, boys are born larger than girls.
- Mom's food. If a woman during pregnancy used high-calorie food, then the child is gaining a lot of weight.
- Psychological and physical state of the mother during pregnancy. Frequent stressful conditions during the period of gestation are reflected both in the health of the baby and in his weight.
- Bad habits of the mother. Drinkers who use drugs and smoke women often have children with underweight.
From these factors, further weight gain of the child up to a year will also depend.
Weight at discharge
For the first few days, little ones lose weight. This is due to several reasons:
- Baby begins to breathe freely. This results in the loss of some liquid.
- In his first days after birth, the baby feeds on colostrum, and in small portions. This lasts until the mother begins to arrive milk.
- Adaptation to the external environment.
For these reasons, the weight of the child at discharge from the hospital differs from the birth weight by about 5-10 percent. And the count of the rate of weight gain in your baby is exactly from this figure.
Norm of weight in children under one year
Finally, you were discharged, and you and the baby are at home. Your child has learned to eat, gradually he develops digestion, as well as heat and air exchange, and the baby begins to grow rapidly.
Weight gain depends on a number of reasons:
- Health. If the baby is sick, he does not eat well.
- Type of feeding. At artificial feeding the weight of the child increases faster, than at thoracal feeding.
- Quantity and quality of food.
- Mobility of the baby.
- Mode of eating. When feeding on demand, the baby is gaining weight better than when feeding by the clock.
- Age of the baby. In the first months the child grows faster, the growth slows down more than a year.
In any case, the specialists established a norm for the weight of a child up to a year. This is averaged indicator, but it is on this basis that the visiting nurses and pediatricians of the children's polyclinic are oriented.
Weight norm in children under one year: table
The average weight gain in the first year of life is as follows:
- In the first month the norm is considered, if the baby adds from 90 to 150 grams per week.
- In the second, third and fourth months, your baby should add between 140 and 200 grams per week.
- In the fifth and sixth month the mass of the baby shouldgrow over the week by 100-160 grams. In six months, what is the norm of weight in children? Up to a year (the table is shown just below), kids increase their own weight very intensively. Normally it is considered, when by the half-year the weight of the child is increased twice from the moment of discharge.
- From the seventh month of life, the increase in mass slows down. By the year the child should weigh three times more than at discharge.
Should I worry if I deviate from the norm?
Quite a frequent occurrence, when the norm of a child's weight is not observed for a year. Kids have either a small, or, conversely, a large increase in weight in comparison with the table. With what it can be connected?
- Physiological characteristics. All children grow differently. Someone is slower, someone faster, and this is normal.
- Growth of a baby at birth. A child with a large growth is gaining weight faster than with a small one. For example, if your baby's height at birth was 52 cm, for him a normal gain in weight per week is 170 g, and if 58 cm is 210 g.
- The sex of the child. Boys usually gain weight more girls.
- Type of feeding. With artificial feeding, children weigh more than babies who are naturally breastfed.
So, you learned what the weight norm in children is up to a year. The table of average indicators should be taken into account, but it should be remembered that there are a number of reasons that affect the set of baby weight, and in each individual case they can be different. Therefore, deviations in the greater or lesser side should not be perceived as a pathological condition. The rates of weight gain are averaged and one should not take them for an ideal.
