The numbers that the scales show when the baby is weighed monthly are not just an indicator of whether the baby is getting enough nutrition. By how the baby is recovering, doctors judge the development of the body as a whole, the presence or absence of diseases.
After the baby is born, he begins to lose weight. The reason for this is birth stress, the process of adaptation to life outside the mother's womb, as well as the release of a large amount of original feces - meconium. This process takes several days. During this time, the baby loses 8-10% of its original weight. You will be able to be discharged from the hospital only after the positive dynamics begins - i.e. the numbers on the scales will creep up.
At first, the weight gain of the newborn is estimated not after a month, but during the first week. On average, he should add about 150 grams. Remember, it is advisable to weigh the child on the same scales, at the same time of the day. For the first month, it is considered the norm to "gain weight" by 600 grams.
For the second and third months, the baby should gain another 600-800 grams. Further, the rate can be calculated using the formula: rate = increase in the previous month minus 50. For example, if at 3 months a child has added 800 grams, then at 4 he will gain 800-50 = 750 grams.
Remember that your baby may gain weight unevenly. For example, a child will gain 450 grams in one month, and 1 kilogram in the next. As a result, the two-month norm will be met.
From about six months of age, the child will begin to add an average of 300-400 grams per month. When he is one year old, the baby's weight should be about 10-12 kilograms.
If weight gain is not as intense as it should be, only a doctor can determine the cause. The baby may not recover enough or not at all due to various diseases. For example, due to gastrointestinal problems - dysbiosis, lactose deficiency or cereal protein intolerance. In this case, the child's stool is disturbed - it becomes liquid, frothy, with undigested pieces of food, abdominal pain appears. If everything is in order with the stomach, metabolic disorders can be assumed.
However, most often, poor weight gain is due to the fact that the baby does not have enough mother's milk or formula. If you want to know how much the baby has sucked, weigh it before and after feeding. Compare the difference with the consumption standards developed by doctors.
