Girls, hello everyone! My daughter didn't breastfeed in the morning, after 10 minutes she vomited like a fountain, then diarrhea started, there is no fever. She feels normal, plays and crawls. We can't call a doctor because we are visiting another city. Our pediatrician advised only to feed her with water and give her breast milk. In case of emergency, call an ambulance. I wanted to ask you what you did in such situations and fed your babies with anything else?
