Was just wondering about this...
She used to tremble a little bit, like the quivering chin and shaking legs, but it seems to be getting more pronounced, especially when she's upset or seems tired. The trembling gets kinda strong, especially in the legs and face. Anyone else dealing with this?
My DS did this when he was born for a few weeks. My pediatrician said it's because he was slightly premature (36w3d) and the coating on the nerves are sometimes not completed in premature babies. I can't remember the term (something that starts with a "m"....myla-something???). Anyway, it eased up when he was about 3 months old and was completely gone at 6 months.
That being said, it is always a good idea to talk to your own doctor about this sort of thing.
