Is it a problem not to drink powdered milk and only drink breast milk?

Patient's question:

The baby is now only willing to eat breast milk and not willing to eat formula. What should be done? Past treatment and effectiveness: Taking some medicine to treat absorption. What kind of assistance is needed: Normal formula feeding

Doctor's answer:

Actually, breastfeeding is natural for infants. Mammals grow up by drinking their mother's milk, and humans are a type of mammal, so it's the same for us. Therefore, if the baby is willing to breastfeed, mothers should feel happy and let him eat as much as he wants.
Moreover, breast milk is not as scarce as you might think. It may be a bit less immediately after giving birth, but as the baby suckles, the milk supply will gradually increase. Mothers should have more confidence in breast milk.
If the breast milk supply is relatively low, the baby may be reluctant to drink formula. To ease the worry about the baby's health, mothers can resort to the simplest method—persistent persuasion.
