your baby’s lip quivers rapidly, particularly their lower lip, then they may have a condition called baby lip quiver. Sometimes, this quivering might be accompanied by crying. In addition, the tremble would resemble that of a cartoon character when it is cold. Many factors contribute to a baby’s lip quiver. These factors could be the common cold or an underlying complex health issue such as an underdeveloped immune system or low vitamin levels. Although you need not worry yet, it
is safe to observe your baby for other accompanying symptoms. Note any unusual and repetitive behaviors or symptoms that are interfering with your baby’s well-being. Read on to know more about the causes behind this lip quivering, the treatment, and the signs to watch out for. Here are some possible reasons for the quivering of lips in babies. Babies
are born with an immature nervous system, which might cause the lower lip to tremble. This is normal and generally subsides in two or three months. During the growing period, the brain sends electrical impulses throughout the body. When this becomes erratic or too quick, it can be too much for the baby’s immature nervous system to handle, causing the lips to quiver
(1). Sometimes, other parts of the body, such as the limbs, tremble and jerk. These could be behind the lip quivering when your baby is young. If the quivering persists after your baby is six months, consult your pediatrician. Sometimes, the baby’s lips also quiver when they use certain muscles for peeing or
passing wind. During such instances, the baby’s lower lip and jaw shake uncontrollably for a few seconds. This is common in newborns, as their muscles are still fragile. If your little one’s lips quiver, check their diaper. Another common reason why a baby’s lips quiver is the cold temperature. You might often notice your baby’s lips quivering, their teeth chattering, and their body shivering when you take them out in the cold or when you put them in
the bathtub. 4. Medical reasonsIn rare cases, baby lip quivering could result from a congenital disability or an underlying medical issue. Some pathological conditions associated with tremors include hypoglycemia, intracranial hemorrhage, and hyperthyroid state (2). Studiesindicate that tremors and quivering of lips could also indicate hypocalcemia, this could be due to an underlying kidney problem or genetic cause for the low level. Such medical conditions are generally accompanied by other symptoms, such as sleep disturbances, poor feedings, irritability, twitching episodes, and generalized seizures (3). If you notice prolonged quivering of lips in your baby and have ruled out nonmedical reasons, it is best to consult your pediatrician. Diagnosis Of Lip Quivering In BabiesYour child’s doctor would do a physical examination to understand the reason behind the lip quivering. They may also ask questions about the baby’s medical history and if you had any complications during pregnancy or delivery. The doctor might also recommend tests such as brain imaging (CT Scan or MRI), EEG, and X-rays to understand the brain’s functioning. Blood tests may also be conducted to understand if there are any deficiencies. Treatments For Baby Lip QuiverIf the quivering of lips is due to an immature nervous system or weak muscles, it usually improves on its own in two to three months.

Lip quivering in newborns is normal for the first two or three months and indicates that the nervous system is still developing.

Check with your pediatrician if you feel concerned about persistent lip quivering in your baby. 4. Could a quivering bottom lip be a sign of a congenital disability? A quivering bottom lip does not always indicate a congenital disability in babies. This may occur since their brain structure and functions are developing. In some cases, it can also be a sign of congenital disability. However, doctors usually exclude other possible causes, such as low calcium levels, muscle movements, and low glucose levels, before considering diagnosis or tests for congenital disabilities (5).
