What is the normal height and weight for a one and a half year old girl?

For babies, the period from when they are born to when they are 2 years old is when their height and weight change the fastest. Parents will already compare babies who are one and a half years old with other children of the same age. The comparison criteria, of course, are height and weight. Although height and weight are affected by genes, the impact of genes is not obvious for babies aged one and a half years old. So, what should be the normal height and weight of a one and a half year old girl?

Generally speaking, the standard height of a one and a half year old boy is 79.4~85.4 cm, and the average standard weight is 10.3~12.7 kg; while the standard height of a one and a half year old girl is 77.9~84.0 cm, and the standard weight is 9.7~12.0 kg.

In addition, the baby's height and weight growth follow basic rules. The birth weight of a normal full-term baby is between 2000 and 4000 grams. In the first three months, the baby's weight increases by 180 to 200 grams per week. At 4 to 6 months, the baby's weight increases by 150 to 180 grams per week. At 6 to 9 months, the baby's weight increases by 90 to 120 grams per week. At 9 to 12 months, the baby's weight increases by 60 to 90 grams per week. During the period of 1 to 2 years old, the baby's weight increases by an average of 2500 to 3000 grams. After the age of 2, the average weight increase is about 2000 grams per year until puberty. If we talk about the multiples of weight gain, the baby's weight at 6 months is twice that at birth, about 3 times that at 1 year old, and about 4 times that at 2 years old.

As for the baby's height growth, the basic rules are as follows: the average height of a newborn baby is about 50 cm, and the height grows fastest in the first year. The average monthly growth is 2.5 cm from 1 to 6 months, and 1.5 cm from 7 to 12 months. At one year old, the height has increased by 25 cm compared to the height at birth, which is about 1.5 times the height at birth. In the second year after birth, the baby's height growth rate begins to slow down, only increasing by 10 to 12 centimeters throughout the year. After that, from the age of 2 to before puberty, the baby's height increases by an average of 6 to 7 cm each year.

The normal height of a one and a half year old girl is 77.9 to 84 cm, and the normal weight is 9.7 to 12 kg. However, if the baby does not meet this standard, don't worry too much. The baby may not meet the standard because of an unbalanced diet. Therefore, in daily life, you should pay attention to the baby's balanced diet, and let the baby exercise appropriately.
