<s>[INST] I have a 17 month old baby who is cutting all 4 of her stomach/eye teeth.Her older sister came home from school yesterday vomiting (I m guessing stomach virus but she only threw up a few times). Today my 17 month old has had a little bit of diarrhea. She hasn t eaten much--mostly just been drinking her cups. Would these issues be her teeth or should I be concerned? [/INST] Hi...teething wont cause diarrhea. Infants keep whatever possible in their mouth to soothe the  pricking sensation due to eruption of teeth. The articles which they put in the mouth need not be clean.Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry.
