We all know that sunbathing for babies brings many benefits. Sunbathing properly will help children absorb vitamin D, thereby helping their bones and teeth to be strong. However, many parents do not know how to sunbathe properly for their children.

Children's bones are initially composed of cartilage, which gradually develops through the process of ossification. Bone formation usually ends around the age of 20. As we grow older, old bone cells are still replaced by new bone cells, but at a slower rate. Over time, our bones become weaker. Therefore, bones need a solid foundation from childhood.

Vitamin D is important for bone health in infants and young children. Premature infants are at risk of vitamin D deficiency, which increases the risk of rickets. Several studies have evaluated the efficacy and safety of early, high-dose vitamin D supplementation in preterm infants to support bone development, the immune system, and early lung development.

Our bodies are built on a skeleton of 206 bones. The shape of each bone is formed from the moment we are born. Children's bones develop and gradually become complete from cartilage. Bone development is complete and the bones are hardened when the child enters adolescence.
