Babies with calcium deficiency can quickly supplement calcium through medication or complementary foods. In terms of medication, calcium gluconate oral solution is a good choice, and it should be paired with vitamin A D supplementation. For food, high-calcium foods such as milk, egg yolks, fish puree, seaweed, and soy milk are good options.
For a 2.5-year-old toddler, doctors recommend choosing calcium supplements with calcium carbonate and taking vitamin AD fish liver oil drops simultaneously to enhance calcium absorption in the intestines.
