When children suffer from rickets with noticeable cranial protrusions and abnormal skeletal changes, it is crucial to timely supplement based on the specific needs of the child for trace elements like calcium, as well as vitamin D. Supplementation of vitamin D and trace elements such as calcium, combined with daily activities like sun exposure, are advisable. Additionally, integrating diet changes by consuming foods rich in calcium supports calcium and vitamin D absorption. Consequently, the cranial protrusions can gradually alleviate or disappear. As supplementation continues and the child ages, the shape of the skull may also change accordingly. In daily life, it is important to prevent skeletal abnormalities in children due to calcium and vitamin D deficiencies by making timely adjustments. (Note: The use of medications should be under the guidance of a professional doctor.)
