What’s best for very low birth weight babies

Posted: 16 Aug 2012 05:15 PM PDT

While the health benefits of breast feeding baby are well known, a new study finds that, for very low birth weight (VLBW) babies, a small amount of fortification can improve growth rates without sacrificing the benefits associated with mother's milk. Human milk provides babies with exactly the right nutrients for growth and also helps protect against infections and diseases. Breast fed babies are less likely to have diarrhea or vomiting, they have fewer chest and ear infections, and long term are less likely to become obese or develop eczema. However, in hospitals human milk is also associated with slower growth in the first few months of life compared to formula-fed infants.
