Often, young mothers, having learned the weight of their newly emerging crumbs, are asked the question: "And how much weight of the newborn is considered normal, and how much should it weigh?".
It is generally believed that the average weight of a healthy, full-term newborn baby is in the range of 2600-4500g. However, in the last decade there has been a tendency to accelerate the biological development of the child. That is why, today the birth of a baby with a mass of 5 kg is not uncommon.
Baby Weight Gain Features
All children grow, and therefore constantly increase their body weight. However, this does not happen immediately. As a rule, during the first week of life the weight of the newborn decreases by 5-10%, which is the norm. This is explained by the fact that the body loses some fluid. In addition, in such a short period of time, the power mode has not yet been established.
Beginning from the second week, the baby begins gaining weight on average 20 grams per day. And with every subsequent day in the second month of life, the baby adds 30 grams daily. Thus, at 4 months the child weighs 2 times more than at birth, and by the year - 3 times.
How to calculate the weight?
Quite often, parents, watching the weight, do not know how to calculate the norm of weight yourself. For this, there is a special formula that allows mother to find out how much her newborn weighs:
Body weight = birth weight (g) + 800 * number of months.
As a rule, the weight of a newborn girl is less than that of a toddler of the same age, and often is no more than 3200-3500 g.
Growth
In addition to weight, an important indicator for newborns is their growth. This parameter directly depends on heredity, as well as on the quality of nutrition of the mother and the condition of her placental circulation. So, for the norm is accepted 45-55 cm.
The growth of the baby also has its own characteristics. More intensively, it increases in the first 3 months of life. At this time, the crumb adds up 3 cm per month.
