Extended breastfeeding

Defined as beyond age 12–24 months

In Western countries extended breastfeeding usually means breastfeeding beyond the age of 12 to 24 months, depending on the culture. Breast milk contains lactoferrin, which protects the infant from infection caused by a wide range of pathogens. The amount of lactoferrin in breast milk increases significantly during the months of 12 through 24 and remains elevated for as long as the infant continues to nurse.
