Children’s height is mainly influenced by genetic factors. If the parents are not tall, the children are usually not tall either, but they can moderately increase their height through postnatal efforts. A balanced diet, eating more vegetables and fruits, and supplementing with protein can help growth. Increasing outdoor activities can boost immunity and supplement vitamin D and calcium to promote bone growth. If necessary, carefully check the level of growth hormone, and if found to be deficient, medication may be required.
