Question
The child suddenly cries loudly after sleeping for 2 to 3 hours at night, lasting about half an hour. The child cannot specify the cause and needs to be comforted for 5 to 10 minutes before falling asleep again. No treatment has been received, and the effect is unclear.
Answer
Crying may be physiological or pathological. Physiological crying is an instinctive reaction, usually caused by hunger, being too cold or too hot, being startled, or having a nightmare. After the parents comfort the child, they can calm down. If it persists, it is recommended to further investigate whether there are pathological factors, such as night terrors or gastrointestinal problems.
