Question
The baby is under 2 months old and suddenly cries from 8 to 9 PM every day, with a regular schedule. The crying is not due to hunger or a soiled diaper. The cause is unknown. Please seek medical assistance.
Answer
Based on the description, the baby may be experiencing anxiety during the evening, known as dusk anxiety syndrome. Most babies become restless during this time, making it difficult for parents to soothe them. This condition is a combination of the baby’s physical and psychological responses, as their developing nervous system struggles to adapt to nighttime fatigue and stress, leading to crying in the evening. For babies under one year old, this is a common occurrence.
