It seems a cold/cough is never just a cold with my twins...at least half the time it turns into an ear infection. Right now both my guys are vomiting, too. Does this happen with anyone else? I took one twin to the doctor yesterday (I was foolish enough to think the other was on the mend), and she said vomiting is consistent with an ear infection. Then today when the other started vomiting, we called the advice nurse first, who said flat out, your doctor is wrong, vomiting has nothing to do with an ear infection. Taking 2nd twin to a different doctor today.
