What is the height and weight of a 30-month-old baby?

In many families today, the baby is the "ancestor". This statement is not an exaggeration, because many parents do everything for their children. From this it can be seen that raising children is not an easy job. Today I will tell you some general information about the height and weight of a 30-month-old baby. I hope it will help you understand it better for future reference.

The average birth weight of a newborn is 3kg, which increases about 3 times within one year after birth. The weight at one year old is about 9kg, and then increases to 4 times the birth weight (12kg) at the age of 2. After 2 years old, the weight increases slowly, with an average increase of about 2kg per year. The weight of children aged 2 to 12 years old can be estimated using the following formula: weight (kg) = (age-2) × 2 + 12 = age × 2 + 8 (kg). Generally, it should not exceed the average plus or minus 10%. If it is below 15%, malnutrition should be considered, and if it is above 20%, overnutrition should be considered.

So the weight of a 30-month-old baby is about 13 kilograms. Here are some specific data:

boy:

Height 82.4cm-105.0cm average 93.3cm

Weight 9.86kg-19.13kg Average 13.64kg

Head circumference 45.3cm-53.1cm average 49.1cm

girl

Height 81.4cm-103.8cm average 92.1cm

Weight 9.48kg-18.47kg Average 13.05kg

Head circumference 44.3cm-52.1cm average 48.0cm

At this time, the baby's various conditions are as follows:

1. Body movement and control: The baby can independently step up the stairs with one foot and then follow with the other foot, and then move the two feet together to climb another step.

2. Exploration and operation: The baby can fold a square piece of paper in half, with the edges and corners basically neat.

3. Language: The baby can use language to simply evaluate and control others. For example, if he sees someone eating without washing their hands, he will say "unhygienic" or when playing games, he will say "you play the little white rabbit and I play the big bad wolf".

4. Social adaptation: The baby can help adults do some things, such as helping adults call others over.

Warm tips: 1. Correct strabismus as early as possible. If the strabismus of babies is corrected before the age of 3, their stereoscopic sense can be restored. If this opportunity is missed, they will become permanently stereoblind.

2. Regular living habits give babies a sense of security: Regular living habits are not only beneficial to the baby's physical health, but also helpful to the baby's psychological development. A regular life makes the baby feel that the outside world is familiar, understandable and controllable, which helps to establish the baby's sense of security.

The above has given you a very detailed introduction to the height, weight and other aspects of a 30-month-old baby. I hope you can pay attention to your baby at this time and let your child win at the starting line. Only when the child develops well can he become smarter and healthier.
