There are three critical periods for a child’s growth: infancy, childhood, and adolescence, which we call the three golden periods for growing taller. These three different periods have different effects on the height in adulthood. The first period: infancy, is the basic stage of the child’s growth Infancy is an important period of child growth and development, but also the basic stage of the child’s growth. Before the age of 2 years, especially at the age of 1 year, nutrition is a key factor affecting the growth of children, and is usually not influenced by genetics. Infants who do not keep up with their nutrition after 8 months of age may affect their adult height. Therefore, nutrition in infancy is very important. This period is very important for the future growth of children. 3 years old and onwards, children can grow 5-7 cm per year, whether it is 5 cm or 7 cm depends on a combination of genetic, environmental and nutritional factors. At this age, children may be partial to food, anorexia, and inadequate nutrient intake, which will directly lead to short head size and reduced height increase during development. Therefore, in this “stable” growth period, parents should pay attention to the child’s annual height growth. The third period: puberty, is the child’s height surge stage 10 to 16 years old is the child’s developmental period, the child’s head is like a spring shoot, “whoosh” straight up. During puberty, due to the catalytic effect of growth hormone and sex hormone, girls can grow an average of 25 cm and boys 30 cm. Parents should be aware that if a girl’s height is not ideal after her menarche and two years after a boy’s voice change, intervention at this time is unlikely to be effective. The child’s three golden growth periods, like dominoes, one ring to another, is a continuous dynamic process, and this stage is the basis for the next stage of growth. In a nutshell, before the age of 2, the supply of nutrition has a significant impact on height; when entering childhood, the role of growth hormone in height comes to the fore; when reaching puberty, sex hormones are quite important for height. So, what should mothers and fathers do in each stage of their children’s development? Infancy: Proper feeding and timely addition of complementary foods are very important. We advocate exclusive breastfeeding within 6 months of age and timely addition of complementary foods when the baby is 6 months old. Otherwise, if no complementary food is added after 6 months, it will be difficult for infants to learn the transition from eating liquid food to half solid food to all solid food, and if they cannot complete this transition in time, they will not be able to swallow solid food and will easily vomit, which will affect their growth and development. In addition, to ensure food diversity, try to exposure to a rich variety of food, not only to ensure a comprehensive supply of nutrients, but also to prevent picky eating behavior later. If the variety of food in infancy is too monotonous, the chances of picky eating and picky eating will be greatly increased in childhood. Childhood: Make sure your child has a balanced diet. Human growth, entirely from the quality of imported food, want your baby to grow tall, a variety of nutrients should be balanced, to ensure that the variety of food eaten every day in 25 to 30 kinds. First, protein every day, in the growth period of the baby, the demand for protein is much higher than that of adults, such as the supply of insufficient will affect the growth of height. Secondly, calcium should be sufficient, if the diet can not often take the amount of calcium required by the physiology, blood calcium and soft tissue calcium is insufficient, it is necessary to take calcium to the bones, and the lack of calcium in the bones, the result will lead to osteoporosis, vertebral deformation, spine curvature. Bones do not get enough nutrition, of course, can not grow normally, let alone grow taller. Thirdly, iron, zinc and copper are indispensable. Children who lack zinc have no appetite for anything, which inevitably affects their growth. Iron is essential for the synthesis of hemoglobin, and copper is a catalyst for the synthesis of hemoglobin. If the food supply of iron and copper is insufficient, the synthesis of hemoglobin will be hindered, and growth, intellectual development and immune function will be affected, and the child may become ill frequently. In addition, growth monitoring is crucial. It is best to measure height once every 3-6 months, and an annual increase of 5-7 cm is considered to be “on target”. If your child’s height is below the third percentile for the same age and sex, with an annual increase of less than 5 cm, it is recommended that you take your child to a pediatric health care or endocrinology department at a specialized children’s hospital for a complete examination and growth hormone treatment under the guidance of your doctor. If girls show any one or more secondary sex characteristics such as breast enlargement, pubic hair and axillary hair growth before the age of 8, or the first menstruation occurs before the age of 10; boys show sexual development such as penis and testicles enlargement, pubic hair growth and voice change before the age of 9, they are considered to be precocious, and should also seek timely medical consultation at this time.
