A baby’s weight gain month by month

People grow more between four months and their first year than at any other time in life. From birth to 1 year of age, their weight will triple.

However, there are variations from month to month and there is no fixed pattern. All children are different. In fact, children can lose weight for a few months instead of gaining weight and this is completely normal.

With this in mind, we have decided to illustrate, step by step, what happens to your baby’s weight gain. This way, you can get a more accurate idea of ​​how he or she is developing.

The baby’s weight during the first week

During the first days of life, the baby does not gain weight. In fact, it is declining. The weight loss should be less than 10% of the baby’s original weight. Some parents may worry about this, but in reality it is a completely normal situation.

This is due to two main factors: one is the elimination of urine and meconium, the baby’s first stool that accumulates in the body during pregnancy. The other is that a newborn baby’s belly is only a little over 5 cm in size. Because of this, he or she may not eat very much at a time.

Children will usually reach their birth weight again by day 15. From that day on, he or she will steadily gain weight.

What happens during the first month?

During the first month of life, the baby’s weight gain is estimated at about 30 grams per day. This is achieved because the baby’s stomach gradually grows as he or she eats more and more. This in turn leads to an increase in breast milk production.

Weight gain between the second and fifth month

From the second month of life, children usually put on about 170 grams per week. This is just under 30 grams a day, or just over 600 grams per month. These months are very important because babies get all their nutrition from breast milk or breast milk substitutes.

After six months of age, the baby begins to accumulate fat

The sixth month of a child’s life can be one of the most beautiful in terms of physical appearance. This is partly due to the fact that children start eating more calories from the fifth month. At six months of age, they will now have their maximum percentage of fat.

Again, this is completely normal and shows us that the infant eats correctly, and according to their own individual needs. At this time, children also begin to get solid foods that supplement their diet. As for their weight, they will put on about 1 kg a month until they are 9 months old.

Weight gain between nine months of age and their first birthday

Almost as if they are getting ready for all the photographs that will be taken on their first birthday, the children will of course reduce this weight gain. At this stage, children will only put on about 200 to 250 grams per month.

Despite this, they will have completed a very successful first year and they will have tripled their weight compared to the first day they saw the light of day.

First of all, remember that proper nutrition, good sleep and all the love you have to offer your child will be the most important factors for its growth. If you are worried that its weight is not increasing enough, or vice versa too much, you should contact your pediatrician as soon as possible.
