<qa>  What is the ideal source of nutrition for most infants?Breast milk is readily accepted as the ideal source of nutrition for almost all infants, including premature or very low birth weight infants. However, these high-risk infants require the addition of fortifiers to their milk in order to achieve sufficient levels of calories, vitamins, and minerals for adequate growth. We are currently using a liquid human milk fortifier which does not provide sufficient protein intake, requiring addition of a liquid protein supplement. A new product has been released which provides sufficient protein in the liquid HMF, without the acidification seen in previous products.
