Breastfeeding could prevent the deaths of more than 800,000 children each year around the world, according to new research.
Children who are breastfed are found to have higher IQs, less risk of infection and lower death rates. It can also protect against diabetes and obesity later in life.
The benefits are there for mothers, too. Women who breastfeed also have a lower risk of breast cancer, ovarian cancer and type 2 diabetes.
However, breastfeeding is not a standard health practice throughout the world. In lower-income and middle-income countries, only 1 in 3 children were exclusively breastfed for the first six months.
Research shows countries with more national wealth breastfeed less than countries with lower incomes.
Researchers say that breastfeeding should be far more common given the health benefits and the fact it's cheaper than buying formula.
