[|Human|] My friends 9 month old baby girl just came back from the doctor for hives - while there, the mother mentioned her quivering lip and chin. The babys always extremely excited to see everyone so we always thought it was just excitement. The doctor then says the only time hes ever seen this happen (quivering lip and chin) is when a disease is present which may prevent the child from ever walking....Im reading just the opposite everywhere online. The 9 month old crawls and tries to walk just like a normal 9 month old. Thank you
[|AI|]  Hi. Thanks for the query. Lip and chin 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. As far as hives is concerned it can be due to allergic reaction and in case if quivering has not happened previously and is happening just now it can be due to the similar cause as of hives. 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. . Consult a Pediatrician and get evaluated. Hope this helps.
