Question
What is the cause of a six-month-old infant’s intermittent neck-sucking and shrugging, accompanied by dry heaving, while all other aspects of the baby appear normal? A Brain Electroencephalogram examination has been conducted, and the results show no abnormalities.
Answer
The neck-sucking phenomenon is not related to urination or defecation. Parents are advised to continue observing the circumstances under which the baby exhibits neck-sucking behavior. If the baby frequently contracts the neck and is accompanied by symptoms such as loss of consciousness, consider excluding neurological disorders. Since the infant is still young and the peripheral nerves are under development, this behavior is somewhat normal to a certain extent. As the baby grows, this phenomenon should gradually improve. Parents can continue to observe, and generally, there should be no major issues.
