What is a contraindication for breastfeeding?

Breastfeeding is generally the best way to nourish infants, but certain medical conditions can pose significant health risks to the child, making breastfeeding contraindicated. Galactosemia is a genetic disorder that impairs the body's ability to metabolize galactose, a sugar found in milk, including breast milk. Infants with galactosemia cannot properly digest this sugar, which can lead to serious complications such as liver damage, cataracts, and developmental delays if they are exposed to breast milk. Therefore, in cases of galactosemia, breastfeeding is contraindicated to prevent these adverse health outcomes.

Other options presented do not represent valid contraindications. The use of cold compresses and handling sore nipples can be part of normal breastfeeding management, and frequent feedings are often encouraged to support milk supply and infant nutrition.
