Weight gain of the baby

Weight gain of the baby

The growth and development of the baby in the first year of life are essential and should be constantly monitored. Therefore, you should go to the doctor often with a baby to measure his or her weight and height and to assess whether they fit into the normal growth and development parameters specific to his age. Get an idea of ​​how much the baby should weigh up to one year, how to weigh it properly and when to worry about it!

How do you approximate your baby's weight gain?

Each baby is born with a different weight or body constitution. Even so, doctors can predict the baby's weight gain from birth, based on standard parameters (growth chart) that are taken into account. There are several methods for predicting weight. But the simplest of them is calculated according to the weight of the baby at birth and his age.
Alina Pop Bogdan, resident physician, argues that, in general, the weight gain of a baby is calculated based on the following model:

  • the baby gains about 750g / month until the age of 4 months;
  • in the next 4 months it weighs about 500 g / month;
  • In the last 4 months of the year, the baby must weigh about 250 g / month;

In other words, the weight of the child will double up to 6 months and triple up to 12 months. This is an indicative model for approximating the weight of the baby during the first year of life. It does not mean that each child will precisely follow this pattern. Let us not forget that each baby has its own rate of growth and development and that no child resembles another.

What factors depend on the baby's weight gain?


Many parents consider that the weight of their baby or newborn is influenced only by the food they receive. Although nutrition is the essential criterion that determines the fluctuation of weight, it also depends on other factors essential in the assessment of weight accumulation:

  • weight curve (ascending, stationary, descending);
  • genetic factors;
  • adipose tissue from various areas of the body - abdomen, face and limbs;
  • appreciation of the skin fold;
  • environmental factors;
  • waist measurement;
  • sex;
  • health status etc.

All these factors influence the weight of the baby. The doctor will determine if, due to personal history, genetic inheritance and medical features, the baby is at a normal weight for his age.

Baby weighing - how and how often should it be done?

Many parents weigh the baby daily, which is not indicated. Either you wait until the next appointment with the doctor, or you weigh it at the beginning of the week, and then at 2 weeks or monthly, but never daily or a few days.
Weighing can often mislead you, especially as babies have times and periods when they lose weight, which might worry you unnecessarily. Although in the first year of life the weight gain of a baby is very large, it should be done gradually, even with periods of stagnation. Your little one does not gain weight every day.
The baby should always be weighed in the morning (before the first meal) or in the evening (before the bath) and completely undressed for a correct weight estimate. If you weigh it the first time in the evening, always try to maintain the balance during this time of the day and do not alternate with the morning. Also, try to do it at the same time always.

When should you worry?

Even if the baby is a few grams below normal or above, you should not worry. These fluctuations are natural, because the child does not grow or grow "like a book".
You should start worrying when there are large differences from the normal weight for your age and development and if there are symptoms associated with:

  • lack of appetite;
  • pallor;
  • altered general state (it is passive, lethargic, apathetic, drowsy);
  • looks weak.

At the opposite end, a child with a weight that far exceeds the normal average for his age is not healthy. Although parents prefer to see their child rather fat or mournful, than weak, it is contraindicated to bend the child and he takes too much weight. Develop a flawed nutrition model, which may have repercussions on his health at maturity.
