As spring is starting to get more and more popular, parents are becoming more concerned about their babies’ height. Recently, we often receive inquiries or messages from parents about their babies’ height, most of them are worried about their babies’ short stature, and some of them even define their babies as “short”. Some parents say that both parents are not tall, so will the baby be even shorter? Today we will talk to you carefully about the things that babies grow up! Height growth rules Height is influenced by genetics, endocrine, and intrauterine growth level, but of course, it is also important later in life. It is important to know that short-term illnesses and nutritional fluctuations do not easily affect height growth, but long-term malnutrition and frequent illnesses can have an impact. The law of height growth is similar to the law of weight growth we mentioned before, the younger you are, the faster you grow. The average length at birth (called “body length” for small month-old babies) is 50cm, and the fastest growth in length is about 25cm in the first year after birth; the growth in length is about 11~13cm in the first 3 months, which is about the same as the growth value in the last 9 months, and the length is about 75cm at the age of 1 year; the growth in height slows down in the second year, about 10~12cm. In the second year, the growth rate slows down to 10~12cm, and the height is about 87cm at 2 years old; after 2 years old, the height grows 6~7cm per year. There are two growth periods: infancy (within 1 year old) and adolescence, so if you grasp these two periods well, you can still grow taller. How do I measure the length of my baby at a young age? Length is the sum of the length of the head, crest and lower extremities, and is not easily measured in a standing position for children under 3 years old. The concept of length is deliberately written out to prevent some parents from making errors when measuring. In the WeChat group, some parents sent pictures of their baby’s length being measured according to the position of the baby’s toes, and most babies are lying on their back in a somewhat tiptoe position. The correct method is to assist the baby’s legs to be straight, with the palms of the feet at an angle of 90° to the plane they are lying on. How to calculate the baby’s future height according to the law of heredity? Many parents worry that their child will be short if each parent is not tall. Here is a formula that parents can use to predict their baby’s future height: Girl = (father’s height + mother’s height – 12)/2 Boy = (father’s height + mother’s height + 12)/2 It does not matter if the calculated value is low, the calculated value will fluctuate up or down a few centimeters. Height is 70% influenced by genetics, and the remaining 30% can be worked on later. What factors affect growth? How can I grow taller? Remember the “4 good things” – eat well, sleep well, exercise well and be in a good mood! Doesn’t it seem too difficult? Let’s explain the “4 good” in detail. Eat well By “eat well” here, I don’t mean to serve good food and drink, but to achieve a balanced nutrition, meat, eggs, milk, vegetables and fruits, eat every day, a wide variety. The nutrients closely related to height growth include protein, vitamin D, vitamin A, calcium and so on. These foods should be eaten in abundance, such as milk or dairy products, vitamin D-rich foods (sea fish, animal liver, egg yolk and lean meat. (Of course, vitamin D should still be supplemented on time.) , vitamin A-rich foods (pork liver, lamb liver, chicken liver, broccoli, carrots, pumpkin, citrus). Do not eat these things or do not eat more – Do not drink carbonated beverages, which may steal calcium from the body. In addition, fried food, puffed food, pickled food should also be eaten less, these foods have low nutritional value, the baby’s appetite is small, eat these, nutritious things instead of eating, but also affect the growth of height. Sleep well Height is influenced by endocrine, growth hormone secretion at night than during the day, the secretion increases at night after sleep, and is related to the depth of sleep, generally in 45 to 90 minutes after sleep. In particular, the peak of growth hormone secretion is from 9pm to 1am and from 5am to 7am. Together with the length of time it takes to put the baby to sleep, as well as the time it takes for the baby to enter deep sleep, parents should put the baby to sleep at around 8:00. Establishing a sleep routine will also help to develop good sleeping habits afterwards. Exercise is good Suitable exercise for babies, not only help the growth of height, for strengthening resistance, disease prevention is also very helpful. Small month-old babies, you can choose big sports exercise; older babies, choose swimming, jump rope, shoot the ball, hoop, etc.. The load is relatively large sports, it is not recommended to expose the baby too early, such as long-distance running, weight lifting, etc.. Good mood Some studies say that being in a depressed state can cause insufficient growth hormone release. If depressed for a long time, it can cause the growth hormone level to drop, which is manifested by delayed growth of height and secondary sex characteristics. Children’s psychology is more influenced by parents, especially parents. If the parents get along well with each other and the family atmosphere is harmonious, the chances of the child having a depressed mood are much less.
