Hi, my daughter is 18 months old. About 10 days ago, we suddenly noticed her mouth was crooked (her left side of the lower lip lower than the right side). She was drinking water when we first noticed it. It went back to normal very quickly. Since then, this asymmetric face has appeared multiple times everyday, most of the time when she was crying or complaining. It all went back to normal very quickly. She eats, chews, and drinks fine. She jiggles and laughs a lot. I don't know if it is due to some neurological disorder. Your advice will be much appreciated!
