The fourth month of the baby has begun, can they start eating complementary foods?

Patient's question:

No

Doctor's answer:

Generally speaking, starting from around four months, in addition to breast milk or formula, it is gradually necessary to feed the baby some vegetable puree, apple puree, banana puree, and other foods. After four and a half months of birth, the iron, calcium, and other nutrients stored in the baby's body have been largely depleted. Feeding only breast milk or formula is no longer sufficient to meet the growth and development needs of the infant. Therefore, it is necessary to add some foods rich in iron, calcium, and vitamins.
