Sunbathing for infants is an effective way to stimulate vitamin D3 synthesis, helping the development of the child's skeletal system. The best time to let your child sunbathe is before 9am, but if you miss this time, you can completely let your child sunbathe in the afternoon.

Baby teeth usually grow when the baby is 6 months old and are completed after 2.5 - 3 years. However, the time of baby teething can still vary within 1 year. Therefore, if the baby is 7 months old and still develops normally, parents should not worry too much, because this may be a physiological delay in teething.

Vitamin D plays an important role in the metabolism and absorption of calcium and phosphorus to form the skeleton. The consequence of vitamin D deficiency in young children is reduced absorption of calcium and phosphorus in the intestines, the body must mobilize calcium from the bones into the blood, causing disorders in the calcification process in bones, causing osteoporosis and rickets in children.

For children in particular, lack of Vitamin D can easily lead to rickets, malnutrition, and increased risk of infection. Lack of calcium will increase vitamin catabolism.

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.

Sunbathing for children has many health benefits, helping the child's body synthesize the necessary amount of vitamin D. Although sunbathing brings many benefits to children, not everyone knows the correct method of sunbathing to achieve optimal results. One of the mistakes mothers make is letting their children sunbathe through the glass.

Vitamin supplementation depends on the needs of each child's age. Therefore, to know what vitamins a 1-year-old, 2-year-old or 3-year-old child needs, parents must understand their child's needs to meet the necessary vitamins and minerals.
