Lip quivering in neonates, characterized by rapid, involuntary trembling of the lower or upper lip, is a commonly observed phenomenon. This physiological tremor often manifests during periods of wakefulness, excitement, or even during sleep. It is typically considered a normal and benign occurrence.
Understanding the underlying reasons for this lip movement provides reassurance to caregivers. While the sight might be initially concerning, these tremors rarely indicate a serious medical problem. This knowledge reduces unnecessary anxiety and prevents potentially disruptive interventions. Historically, such movements may have been misinterpreted, leading to unwarranted medical examinations and parental stress; accurate information is therefore crucial.
