What should I do if a four-month-old baby is calcium deficient?

Patient's question:

No

Doctor's answer:

The child is 4 months old and can only use liquid calcium. Gluconate calcium can be used, with two vials per day, one in the morning and one in the evening.
During this period, fish oil can be added to enhance calcium absorption. Now that the baby is 4 months old, solid foods should be gradually introduced. Start with foods rich in calcium, such as egg yolk, juice, and tofu. Begin with small amounts, moving from one type of food to multiple, and from fine to coarse textures.
