Which of the following is a medical contraindication for breastfeeding?Multiple ChoiceThe infant was born by Caesarean section.The mother has gestational diabetes mellitus.The infant has galactosemia.The infant is born preterm.

The correct answer is: The infant has galactosemia.

Here's why:

1. The infant was born by Caesarean section: This is not a contraindication for breastfeeding. While it might be a bit more challenging due to the mother's recovery, it is still possible and beneficial to breastfeed.

2. The mother has gestational diabetes mellitus: This is also not a contraindication for breastfeeding. In fact, breastfeeding can help both the mother and baby regulate their blood sugar levels.

3. The infant has galactosemia: This is a contraindication for breastfeeding. Galactosemia is a rare genetic metabolic disorder that affects an individual's ability to metabolize the sugar galactose properly. Breast milk contains lactose, which is broken down into glucose and galactose. Therefore, a baby with galactosemia cannot be breastfed because they cannot properly metabolize the galactose found in breast milk.

4. The infant is born preterm: This is not a contraindication for breastfeeding. In fact, breast milk can provide essential nutrients that can help a preterm baby grow and develop.
