What does the presence of witch's milk in infants typically indicate?

The presence of witch's milk, which refers to a small amount of milky fluid that can be expressed from an infant's nipples, is typically related to high maternal hormone levels during pregnancy. This discharge occurs due to the influence of estrogen and other hormones that cross the placenta, stimulating the infant's mammary glands even before birth. This phenomenon is generally harmless and resolves on its own, highlighting the impact of maternal hormone levels on the newborn.

In contrast, other options do not correctly reflect the cause or implications of witch's milk. For example, the presence of witch's milk does not indicate a breast infection, which is characterized by symptoms such as redness, swelling, or pain. Similarly, it is not linked to dehydration in the infant, as dehydration would manifest in different signs such as fewer wet diapers or a dry mouth. Lastly, witch's milk occurs independently of how much breastfeeding is taking place, as it is a hormonal response rather than one caused by breastfeeding practices.
