The girl's ideal weight varies with age and should be checked monthly by the pediatrician during the first year of life, as too low or too high a weight can impair the child's development and growth.
The child's ideal weight is not a single value, varying between two acceptable values and it is influenced by the girl's daily diet, physical activity and individual genetics.
Generally, weight gain in the first 12 months is faster and then it is normal to increase more slowly, because the child becomes more active, starting to walk and expending more calories, slowing down the weight gain.
In addition, girls' development is not all the same and a girl at one age may not gain as much weight as another girl at the same age, for example. Therefore, it is important to analyze each case and not make comparisons between girls.
Girl's weight table for age
The following table shows the weight values appropriate for the girl's age according to the World Health Organization. However, if the girl does not have the weight indicated in the table, it does not mean that she is not healthy.
| Age | Weight | Age | Weight | Age | Weight |
| 1 month | 3.2 - 4.8 Kg | 7 months | 6.8 - 8.6 Kg | 1 year and half | 9 -11.6 kg |
| 2 months | 4.6 - 5.8 Kg | 8 months | 7 - 9 Kg | 2 years | 10 - 13 Kg |
| 3 months | 5.2 - 6.6 Kg | 9 months | 7.2 - 9.4 Kg | 3 years | 11 - 16 Kg |
| Four months | 5.6 - 7.2 Kg | 10 months | 7.4 - 9.6 Kg | Four years | 14 - 18.6 Kg |
| 5 months | 6.1 - 7.8 Kg | 11 months | 7.8 - 10 Kg | 5 years | 15.6 - 21.4 Kg |
| 6 months | 6.4 - 8.4 Kg | 1 year | 8 - 10.2 Kg | + 5 years | > 15 Kg |
Girl's weight percentile curves
The most important thing is to check if the girl gains weight regularly, as not gaining weight, as well as suddenly increasing or decreasing weight, may be related to a health problem, such as diabetes or hyperthyroidism, for example.
Generally, the girl's age percentile curves for age are used by the pediatrician to check the evolution of weight as the child grows and, most importantly, the girl keeps her weight following the same percentile curve.
It is also important that balanced growth occurs not only between weight, but also between head height and perimeter.
Use the following calculator to find out the girl's ideal weight from 2 years of age:
Attention: This calculator is not suitable for calculating weight before that age, being more appropriate to follow the pediatrician's instructions and the information present in the baby's handbook.
In addition, to know the ideal weight of the girl after 5 years of age, other tables or percentile curves should be consulted because in addition to age, the girl's height will also influence the appropriate weight.
