If 9 months of pregnancy have passed without complications, the child is likely to be born with a weight of 2,600–4,000 g (the average weight of newborn boys is 3,500 g, and that of girls is 3,350 g). Weight at birth less than 2.5 kg is considered low, which is often associated with intrauterine hypotrophy – growth retardation, and a newborn with a mass of 4 kg or more is called a large fetus.
Immediately after birth, most babies lose from 3 to 7% (less often – up to 10%) of the initial mass. This is due to the natural loss of fluid through breathing, as well as feces and urine. The reasons for the pronounced loss of weight (more than 10%) can be difficulties in establishing breastfeeding.
But in a week, babies, as a rule, make up for losses. In the first month of life, the child gains relatively little in the mass (400–600 g), which is explained by its physiological loss after birth.
From the second month of life, the rate of increase in body weight is maximum for the entire first year of life – an average of 700–1000 g per month up to 6 months and somewhat less in the second half of the year (approximately 600–800 g), so by the year the baby weighs an average of 8–11 kg
Changes in growth manifest themselves more slowly than weight changes. If for the first year the kids manage to triple their weight (from an average of 3 kg to 8–11 kg), then they grow “only” one and a half times (usually from 50 to 75 cm).
Children grow the fastest in the first three months, adding 3–3.5 cm in each of them; then the rate of increase may decrease slightly: 2.5 cm per month until the end of the half year, and then 1–1.5 cm per month up to a year.

Measurement and Weighting Frequency
If a baby was born full-term, with a normal body weight for a newborn, the baby has a good appetite, he is not sick and his development goes smoothly and safely, then changes in his weight and height should be monitored no more than once every 1-2 weeks for 1 –2 months of life, while the process of formation of lactation and “mutual addiction” is underway, and starting from the 2nd-3rd month – no more than once a month. With the same regularity, you can monitor the growth of the baby.
Further, if the child develops well, it is possible to carry out these procedures only during special medical examinations.
Today on the market there are scales of the following types: mechanical and electronic. As for the design, the difference between them is small, and the somewhat higher cost of electronic scales pays off by the simplicity of their use and a wider compared to the mechanical set of functions. When buying, be sure to ask what weight the scales are designed for, and also pay attention to the availability of additional devices.
So, for example, some manufacturers attach to the scales a special scale, with which you can also measure the height of the child.
Read the instruction manual carefully. Find information about the maximum error of the scales, their weighing limit and power source.
It is better if the scales can work both from batteries and from the network (if we are talking about electronic scales). While using the scales, do not forget about safety rules: babies should not be left unattended, as they can fall out of the weighing bath; Older children should not be allowed to jump on the scales, as this can lead to injuries or damage to the scales.
Scales are equipped with a removable tray designed for weighing babies. The weight of any item up to 0.5 kg (diapers, etc.) can be subtracted using the “TARA” function to get the exact weight of the child.
Scales can be used as ordinary floor scales to measure the weight of more adult children weighing up to 50 kg. The result of the last weighing is stored in memory.
Practical and super absorbent diapers help create comfort for your children. They are made using high-quality European raw materials.
Indispensable when changing a diaper, when weighing the crumbs on the scales. Protect the surface of the crib, stroller or car seat from getting wet.
The Micuna changing table is equipped with lockable wheels and moves easily in space. The combination of natural wood – beech – and high-quality MDF material is absolutely safe for the health of the child.
Changing table will fit into the interior of any room. His real highlight is Swarovski crystals.
