Why Is My Baby Quivering Her Bottom Lip?

    When most people imagine a baby, they’re mostly thinking of a tiny angelic human peacefully resting in a crib. In reality, infants are noisy, restless; they have interesting sleeping postures, and sometimes their lips quiver. Mothers are very observant when it comes to their children. Luckily, noticing your baby quivering her bottom lip is a common experience for mothers, especially amongst lactating women. 

    What Causes Bottom Lip Quivering?

    The Brain

    The scientific community suggests that when your baby quivers her bottom lip, it results from a developing brain. In this case, you should not worry because the quivering will disappear naturally within a month or so. The only time it should be a concern is when it goes on longer than three months. 


    Sometimes you will notice that your baby quivers her bottom lip whenever they use specific muscles of their body. The common instances include relieving themselves, passing wind, and response to temperature change. Your baby’s jaw and lower lip may shake uncontrollably for a few seconds when their body gets exposed to a cold environment. 

    It is common for infants to struggle with peeing, passing wind, and doing a number two because their muscles are still fragile.  

    Medical Condition

    Lip quivering could be a symptom of a severe congenital disability but don’t be in a hurry to conclude this without consulting a pediatrician. When seeking the opinion of a doctor, it is helpful to approach more than one specialized professional. That way, you can be 100% sure before deciding on a particular treatment.

    Your child may be suffering from a deficiency in calcium, or their blood sugar levels are not balanced. Studies have shown that infants who did not receive enough oxygen during birth end up with defects revealed later by lower lip quivering.

    How To Treat Bottom Lip Quivering?

    Until a doctor confirms the lip-quivering as a problem, you should not be worried when your baby quivers her bottom lip. There are times the habit may be a concern to you, and this is what you can do:

    • Cover them in warm clothing and ensure that their bathwater is of optimum warmth. 
    • Avoid exposing your baby to cold environments for long durations. 
    • Be patient and note the exact conditions that cause the quivering. 
    • Hold them close to you and gently tap on the child’s lips.

    The lower lip quivering should disappear immediately; you gently tap on the infant’s lips. What if this does not work?


    Healthy eating is equal to a healthy brain, and your child should not be the exception. It is essential that when you are exclusively breastfeeding, you should be on a balanced diet. When you eat well, your baby will enjoy more nutritious breast milk, and their nervous system will develop naturally. 

    A child that is being fed well is likely to experience less low lip quivering during their infancy. Several studies have revealed that healthy eating can alleviate and, in some instances, prevent birth defects. 

    Medical Treatment

    After taking your baby to a doctor, they might be diagnosed with a convulsion type that can be treated with drugs. In extreme incidences, physical therapy and punctures might be prescribed by a doctor. The pediatrician needs to carry out thorough testing to rule out possible seizures. The good news is that certain conditions can be better managed when detected early. 

    The False Alarm

    The measures highlighted above should not apply when your baby quivers her bottom lip because they are crying. You should also not be troubled when it only takes two seconds and does not occur as often.  It is up to a medical professional to rule out any medical factors behind this behavior. 

    Your baby’s quivering bottom lip could either be a natural developmental response or a symptom of an underlying illness. Before you decide that it’s a normal thing, consider the medical history of the child. If health complications occurred during birth, then take the child for a checkup immediately you notice the quivering. Be thorough with routine medical checkups because early detection is lifesaving for children.
