I took Miriam to the pediatrician, and we found out that NOT ONLY does she have another ear infection, but she ALSO has bronchiolitis. She endured a 10-minute albuterol treatment with the nebulizer (which she screamed through) and an antibiotic shot that I was promised would be beefier than the amoxicillin she received for her other two ear infections.
We're hoping this will clear things up for her so she can have her surgery in a week or two.
