My 15 month old daughter woke up vomiting this morning. At first it was a bright yellow color, now it has turned into a white foam with bubbles. I have taken her to the doctor and he says it's a virus.It seems that she is having a hard time getting the vomit out and then she gets the hiccups. I am afraid the type of vomiting she is experiencing is not normal and I am considering a 2nd opinion. Any help would be appreciated.
