My daughter has had a ear infection for almost a month now this is her 3rd Antibiotic she has been on she cries and cries she doesn't sleep good at night from coughing so much she chokes where she coughs so much 
RSV is going around from what my doctor says . My questions is 
Is it normal for a doctor to put a baby that's only 4 months old on that many antibiotics and not be concerned about her cough that she said sound like bronchitis ?
