Your baby’s weight gain per month

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

However, there are variations from month to month and there is no set pattern, all babies are different. In fact, babies may lose weight instead of gaining weight for several months, which is completely normal.

Taking this into account, we have decided to tell you step by step what happens to your baby’s weight gain. This way you’ll have a more accurate idea of ​​how he’s progressing.

Baby’s weight in its first week

In the first few days of life , a baby does not gain weight, it actually decreases. The weight loss is about 10% of the original weight. Some parents will start to worry about this, but in reality it is a perfectly normal situation.

This is due to two main factors: one is the elimination of urine and meconium, the baby’s first stools that have accumulated in his body during pregnancy. The other is that a newborn’s stomach is only about 5 centimeters. Because of this, he cannot eat much at once.

Babies will usually reach their birth weight by day 15. From then on, it will gradually increase.

What happens in the first month?

During the first month of life, a baby’s weight gain is estimated at 28 grams per day. This is achieved because a baby’s stomach gradually expands as he eats more and more. This, in turn, causes an increase in breast milk production.

Weekly weight increases between the second and fifth month

From the second month of life, a baby gains about 200 grams per week. This is just under 30 grams per day or about 600 grams per month. These months are very important as babies depend solely on breast milk or formula.

After six months, the baby starts to gain body fat

The sixth month of a baby’s life can be one of the most beautiful in appearance. This is partly due to the fact that children consume more calories from about the fifth month. When they are six months old, they now have their maximum body fat percentage.

Again, this is completely normal and shows us that babies are fed correctly and according to their own individual needs. At this time, children will also be introduced to new foods that complement their diet. In terms of weight, they gain about 450 grams per month until they are 9 months old.

Between nine months and their first birthday

It’s almost like they’re getting ready for their first birthday photos, as the baby’s weight gain will naturally diminish. At this stage, children only gain about 200 to 250 grams per month.

Despite this, they have completed a very successful first year and have tripled in weight from day one.

Finally, remember that good nutrition, good rest and all the love you have to offer your baby will be the most important factors in his growth. If you are concerned that his weight is not gaining or increasing insufficiently, contact your pediatrician as soon as possible.
