Height problem of a three-year-old and four-month-old baby

For many mothers, one of the issues that they are very concerned about is their children's height. Many people think that this is related to genetics, but in fact, genetics only accounts for a small part of a child's height. In fact, acquired nutrition and environment also play a very important role. And children's sleep and diet are also very important. Therefore, parents who want their children to grow tall may wish to read the following content.

Many parents hope that their babies will have a healthy body and ideal height in the future, especially those who are shorter.

The baby's height is a complex issue, involving genetics, environment, diet, exercise, sleep, emotions and other aspects. Too much emphasis or neglect of any one link will not achieve the desired result. If you try to force the issue, problems will be more likely to occur. Three questions about height:

Q1. Is there any relationship between a baby’s height at birth and his future height?

The average height of a standard full-term baby is 49-51 cm. Boys are usually taller than girls, but 46 cm is normal. There are also full-term babies who are over 52 cm tall.

A baby who is 46 cm tall at birth does not necessarily mean that he will be short when he grows up, and a baby who is 52 cm tall at birth does not necessarily mean that he will be tall when he grows up, because the baby's height at birth is related to many factors of the pregnant mother, such as age, number of pregnancies, the pregnant mother's physique and pelvic size, nutritional status and mental state, etc. Therefore, it is generally believed that there is no obvious relationship between a baby's height at birth and his future height as an adult.

Q2. What are the rules for height growth of babies aged 0 to 3 years?

Although the baby's growth and development is a continuous process, the growth rate varies from stage to stage. The specific rules are:

Newborns (from birth to 28 days): Height increases by approximately 4 cm.

Q3. Can the height of a baby at 2 to 3 years old be used to predict his adult height?

There are many traditional methods to predict a baby's height, and most parents are aware of them. In recent years, foreign experts have found that the height of a baby at the age of 2 to 3 can be used to roughly estimate the height of the adult, which is worth learning from. The specific calculation formula is as follows:

Formula 1:

Girls: Adult height (cm) = 0.545H2 + 0.544A + 25.63

Boys: Adult height (cm) = 0.545H2 + 0.544A + 37.69

(Note: H2 is the height at the age of 2, A is (father's height + mother's height)/2)

Formula 2:

Girls: Adult height (cm) = 1.29 × H3 + 42.3

Boys: Adult height (cm) = 1.27 × H3 + 54.9 (Note: H3 is the actual height measured at 3 years old)

Infant (1 month to 1 year): This is the fastest growth and development stage for babies. From the 2nd to the 3rd month, the height increases by 3 to 4 cm per month; from the 4th to the 6th month, the height increases by 2.5 cm per month; after the 7th month, the height increases by 1 to 1.5 cm per month. The total height increase for the whole year is about 25 to 28 cm.

Infants (1 to 3 years old): Children aged 1 to 2 years old grow 10 to 12 cm in height per year. At the age of 2 to 3, height increases by 5 to 8 cm each year.

Parents can compare the above values ​​to see if the baby's height increase rate conforms to this rule. If a baby aged 1 to 2 years old increases less than 10 cm in a year, and a baby aged 2 to 3 years old increases less than 5 cm in a year, it indicates that the baby is growing slowly; if a baby aged 1 to 2 years old increases less than 8 cm in a year, and a baby aged 2 to 3 years old increases less than 4 cm in a year, you should ask a health doctor to check and find out the reason.

The above is a detailed analysis of some issues that affect children's height. I believe that after reading the above content, parents must have a certain understanding of the baby's height issue. I believe that everyone will no longer have so many confusions. If you want your babies to grow tall, then moms and dads must work hard to improve their diet and pay attention to their sleep.
