My 16 month caught the stomach flu. vomiting began wed 27th and continues to vomit breast milk every night. she is barely eating. also has diarrhea.

See the doctor: With small children, you don't want to take any serious risks - it sounds like your child is dehydrated. I would call immediately to try and be seen. Small children don't have the 'reserve' that adults have to fight through diarrhea/gastrointestinal illnesses. Is she making 'wet' diapers? What about tears? You can tell her volume status by some of these signs -I'm concerned about it, so go to docs
