In the first year of your baby's life, he or she will go through many diet changes. Breast milk or formula will be the main source of nutrition up until four to six months of age. After that, solid foods should be slowly introduced into their diet. By the end of the first year, 50 percent of a baby's nutrition will come from complementary foods; the rest from breast milk or formula.
Infant nutrition goes beyond just satisfying nutritional needs, though. This is also an important time, because research has shown that eating habits established during the first two years of life carry through into adulthood. That is why establishing good eating habits from the start is critical.
