Height of one year old baby

One-year-old infants and toddlers are in a period of rapid development in height and weight. At this time, parents will intuitively see that their baby's height is increasing day by day, which is several times higher than when they were just born. Moreover, the height standards for boys and girls are completely different. Boys are generally taller than girls, so parents should pay more attention to supplementing their nutrition during the growth and development period to ensure balanced nutrition.

12 months old male: 71.0～81.2cm; female: 69.0～79.6cm;

15 months old male: 74.1～84.8cm; female: 72.2～83.3cm;

18 months old male: 76.7～88.1cm; female: 75.1～86.7cm;

21 months: male: 79.1～91.2cm; female: 77.8～89.8cm;

24 months: male: 81.3～94.0cm; female: 80.3～92.6cm;

2.5-year-old male: 85.8-98.7cm; female: 84.9-97.7cm;

3-year-old boy: 89.9～103.2cm; girl: 88.8～102.3cm;

1. Nutrition. Height is the sum of the head, spine and lower limbs, and is an important indicator of bone growth, especially long bone growth. When a child's nutrition cannot meet the needs of bone growth, the rate of height growth will slow down. Nutrients closely related to bone growth include vitamin D, calcium and phosphorus. Deficiency of iodine and zinc can also cause young children to be short.

2. Sleep. Growth hormone secreted by the pituitary gland is an important hormone that stimulates children's growth. The secretion of human growth hormone is unbalanced within 24 hours a day, and its secretion is higher during sleep than when awake. Lack of sleep will affect the growth of young children. Generally, children aged 1 to 18 months need 13 to 15 hours of sleep per day and night; 18 months to 3 years old, 12 to 13 hours. The amount of sleep children need each day varies greatly from person to person. If a child sleeps less but his mental, emotional and growth and development are normal, there is no need to force it.

3. Exercise. Exercise can promote blood circulation, improve bone nutrition, accelerate bone growth, make bones dense, and promote height growth. Children under 3-4 months old should lie on their stomach several times a day to promote whole-body activities, and should develop basic abilities such as turning over, crawling, standing, and walking as they grow older. Children should not be held or sit for too long. It is inconvenient for children to move their whole body while being held, and sitting for a long time will affect the development of their lower limbs. At the same time, after children learn to sit, they are often unwilling to learn to roll over and crawl.

4. Disease. Many diseases can affect children's height growth. Generally, acute diseases only affect weight, while chronic diseases can affect height. If, after long-term measurement and observation, a child's height is always more than 10% lower than the average height of children of the same age, it is called growth retardation; if it is more than 30% lower, it is abnormal and should be diagnosed and treated in time.

5. Genetics and gender. The height of a considerable number of children is affected by genetics. In terms of gender, boys are generally taller than girls of the same age.

6. Living environment, social culture, and climate region. According to a survey, children in northern my country are taller than those in southern China. Children in areas with high living environment and social and cultural levels tend to grow taller.
