Calcium supplementation for infants should involve regular sun exposure, breastfeeding, and the introduction of complementary foods.

1. Regular Sun Exposure: Exposing infants to sunlight is a natural way for them to obtain vitamin D, which facilitates calcium absorption.

2. Breastfeeding: Breast milk is one of the primary sources of calcium for infants and contains easily absorbable calcium and other essential nutrients.

3. Introduction of Complementary Foods: When infants begin to consume complementary foods, caregivers can choose calcium-rich foods that also provide other essential nutrients, supporting the infant's overall development.

4. Choosing Appropriate Calcium Supplements: If dietary intake cannot meet an infant's calcium requirements, a physician may recommend calcium supplements. Common calcium supplements for infants include calcium gluconate oral solution and pediatric calcium carbonate D3 granules.

5. Vitamin D Supplementation: Vitamin D is crucial for calcium absorption. In addition to sun exposure, it can also be obtained through diet or vitamin D supplements.

Parents should also be cautious not to over-supplement calcium during the process, as excessive calcium intake may interfere with the absorption of other nutrients or lead to problems such as kidney stones. Ensuring a diverse diet for the infant and avoiding an overreliance on high-calcium foods will help maintain adequate intake of other essential nutrients.
