Experts say breast milk is the best food for babies. In fact, the World Health Organization says it is the only food babies should get during the first six months of life, in most cases. Breast milk is especially important for babies born too early. Sometimes these premature babies must stay in the hospital for many weeks.

There are several reasons some mothers may not be able to breastfeed. Some are not able to make enough milk. Others might be taking medicines or have medical problems that prevent the process.

James Cameron is a doctor who treats newborns at Lutheran Children's Hospital in Fort Wayne, Indiana. He says breast milk is almost like medicine.
