How tall is a normal baby at three months old

Recently, wherever mothers gather, you can hear them talking about the height of three-month-old babies. This has aroused a lot of curiosity. Why do they only discuss the height of three-month-old babies? Why not six months, nine months, etc.? After looking up relevant information, I finally understand why mothers are so happy to discuss the height of three-month-old babies. The editor will introduce it to you, and I hope everyone can understand it.

1. Baby's height and genetics

If parents are short in height, it is predicted that their children will also be short in height in the future, but the actual situation may not be so. No matter how good the genetic genes are, if you don't eat well or are malnourished, you won't grow taller. Even if you inherit the gene for short stature, you can still promote your child's growth by properly controlling environmental factors. Parents' genetic factors only play a 20%-30% role in growth, and the rest is determined by factors such as nutrition, exercise, and living environment. Some experts believe that genetic factors may play a greater percentage than this ratio, but nutrition and exercise are generally recognized as determinants of growth. In addition, children nowadays are under great psychological pressure from an early age, and relieving stress in a timely manner is also a very important factor. Going to bed on time at night can promote the secretion of growth hormone. Some people say that you can grow taller as long as you sleep well.

2. Standard calculation method for height and weight of infants and young children

For babies aged 4 to 6 months, their weight generally increases by an average of 700 grams per month, and their height increases by an average of about 2.4 centimeters per month. The head is also in its fastest period of development, with the head circumference increasing by an average of about 1.5 cm per month. By 6 months, the head circumference can generally increase by 9 cm. The increase in subcutaneous fat makes the chest circumference grow faster than the head circumference.

3. Secrets to baby's height growth

For babies of this age, parents mainly help them with passive exercises: the baby lies on his back on the bed, and the father or mother helps the baby with rhythmic movements such as moving the head left and right, flexing and extending the upper limbs, flexing and extending the lower limbs, and bending the body upwards and downwards. Do each part at a slow pace for about 5 minutes, being gentle. When parents implement this method, they can talk to the baby. There is no limit to the content of the conversation. Even though the baby may not understand, the baby is happy to listen, which is very helpful in cultivating the baby's good mood.

4. Reasons why babies don’t grow taller

Height reflects the baby's long-term nutritional status and is also related to genetics. Weight reflects recent nutritional status. Judging from the baby's current height, it is within the normal range. Judging from the baby's weight gain rate, the weight should increase by more than 600 grams per month from 4 to 6 months, and more than 250 grams per month from 6 to 7 months, but your baby's weight has not increased; considering the actual value of the baby's current weight, it is mild malnutrition. Therefore, your baby's weight is not increasing at a normal rate or is not actually increasing.

5. Baby’s diet

Generally, a 7-month-old baby should be given 1 serving of complementary food and 1 serving of fruit every day in addition to 800 ml of milk. The complementary food includes 2 spoons of thick porridge, 2 spoons of vegetables, half a spoon of meat or half an egg. Your baby is already 7 months old and it is not enough to only add rice cereal and eggs. It is recommended that you feed your baby 2 spoons of vegetables every day and add fruit once a day to meet your baby's needs for vitamins and minerals. You can also feed your baby meat puree, liver puree, fish puree and eggs alternately so that your baby can get a variety of nutrients.

After reading the above knowledge, I believe everyone has understood the issue of the height of a three-month-old baby. Even if the child's genetic factors are not very high, mothers can pay a little attention, work hard on the baby's diet and exercise, give the child more protein-rich foods, and pay attention to the supplementation of trace elements such as calcium, iron, zinc and selenium. The child will grow taller and taller.
