Hello there,My 10 month old sons bottom lips quivers almost all the time.  I am not noticing any sort of pattern like when he is cold, when he gets upset, etc.I spoke to my sons doctor who only suggested that I keep a log off of when it happens.  Honestly, it is continous so not sure how that is helpful.What are your thoughts about what this may be?
Hi. Welcome to Chat Doctor. As per your complaint lip quiver in infants is commonly seen as they have an immature nervous system, and it is resolved as the child grows and reaches further milestones. But in case if the quivering does not resolve, or it becomes more severe you should consult a Pediatrician and get evaluated and a clinical evaluation and investigations like MRI Scan and blood tests to check for any nerve related problem or nutritional deficiencies and syn Chat Doctor. . As of now it does not seem t be anything related to any pathology, so you should wait for at least a month and watch. Hope this helps.
