How long does the baby need calcium supplementation?

To prevent calcium deficiency, vitamin D3 supplementation should be started a few days after birth and can continue until about two years old. As your child increases outdoor activity and eats a balanced diet, vitamin D3 can be discontinued. During the course of taking vitamin D3, if there is plenty of sunshine in summer, vitamin D3 can be temporarily discontinued or reduced. The normal dose of vitamin D3 is 400U/day, the maximum dose of premature infants can be 1000U/day, after 3 months to 400-800U/day. If vitamin D deficiency rickets has occurred, vitamin D3 dosage can be 2000-4000U/day, continuous service after a month to 400-800U/day. We need to supplement vitamin D3 and give appropriate calcium to help improve symptoms and promote bone development. At the same time, we need to adjust the dietary structure, increase dietary sources and calcium intake. Giving children more sun exposure is a simple and effective way to prevent and treat vitamin D deficiency rickets. We must ensure that children spend more than 1-2 hours outdoors every day.
