Is it harmful to the growth and development if the milk is short?

Patient's question:

Milk is short, will it interfere with the baby's nutrition and growth and development? How to need to digest many other nutrients, if need, what to supplement those things well

Doctor's answer:

For 5-month-old babies, breast milk is the best food. However, if the mother's milk is not enough, cow's milk can be mixed with it for feeding within the first four months. Since you have stopped breastfeeding, if you provide complementary foods promptly and appropriately, it will never interfere with the baby's nutrition and growth and development.
Based on a puree diet, such as: vegetable puree, fruit puree, iron-fortified rice cereal, and formula milk.
Main meal: Breast milk or formula milk
Snacks: Complementary foods should gradually increase
Potty training: Use a small spoon to feed
The principles for providing complementary foods are:
1. Start with small amounts to make it easier for the baby to adapt.
2. Begin with thin consistency and gradually increase to thicker and coarser textures.
