What typically leads a baby to experience "caida de la mollera"?

The phrase "caida de la mollera" refers to a condition in infants characterized by the depression of the fontanelle, or soft spot on the top of the baby’s head. This condition is often attributed to severe dehydration, which can occur when an infant is not receiving enough fluids, has been vomiting, or experiencing diarrhea. In this context, dehydration can cause physical changes in a baby's body, including the sinking of the fontanelle, leading to the appearance associated with "caida de la mollera."

This understanding is rooted in traditional beliefs that correlate physical health symptoms with specific cultural explanations. While excessive admiration, touch from a physician, and exposure to witches might be factors discussed in cultural narratives, it is the physiological state of the baby due to dehydration that most directly leads to the observable effects associated with this condition. Therefore, recognizing the serious implications of dehydration is crucial in addressing and treating potential health issues in infants.
