We all know that breastmilk is normally the best food for full-term babies and some premature babies. However, when breastmilk is insufficient, or when the mother or the baby suffers from certain illnesses that prevent breastfeeding, artificial feeding is needed to ensure the baby’s nutrition and development. The “ideal” artificial diet should meet the nutritional needs of a healthy infant; be well tolerated without causing metabolic distress or biochemical disorders; and have no immediate or long-term adverse effects. Modern infant formulas are getting closer and closer to meeting these standards. Some parents think that the fresher the milk, the better, and choose fresh milk to feed their babies, but in fact, fresh milk is not suitable for feeding infants within 1 year of age due to its many disadvantages.

Larger infant formula (6 months and above), suitable for babies over 6 months old, is also a milk-based formula.
