Just now a friend asked me in WeChat: Some people said on the Internet that every year from March to May is the accelerated growth period of children, the average growth of 1.37 cm, significantly higher than other seasons, this period will often hear children say leg pain, especially at night when sleeping pain, this is called growing bone pain. Mothers should be alert to the fact that this is the time when babies are seriously deficient in calcium! Take advantage of the good spring season and give your child a calcium supplement! Q: Is there such a thing? A: Children’s growth and development is faster in spring, but the growth of 1.37cm a month depends on the age. Adolescent children can grow more than 1 cm a month, preschool or school-age children can grow 0.5 cm a month is good. Because of the rapid growth, some children may experience pain in the knee and ankle joints at night, called growing pains. In spring, when children get more sun, they will have more vitamin D. Proper calcium supplementation is also necessary. However, calcium supplementation alone is not enough, it is better to supplement amino acids, protein, vitamins, zinc and other nutrients at the same time. So more milk and more vegetables and more outdoor activities are the best choice!
