Thanks ladies!
Her cough got worse so DH just took her in and yup, ANOTHER ear infection. I am so frustrated. I am also annoyed because I feel like the doctor's office should have been scheduling follow up appointments (with any babies, not just mine!) to check to see if the infection is cleared. I am thinking about looking for a new doctor because this experience has led me to feel like they just shuffle us in and out and don't really care about Avery's health.
So anyway, she had to get an antibiotic shot (my poor girl

) - I am glad DH and MIL had to deal with that and not me. I hate seeing my girl in pain. But I am glad we don't have to deal with trying to force feed her oral antibiotics.
They also gave us the name of an ear, nose & throat specialist per DH's request, but apparently the appointments for this place are 3 months out so it's possible she'll have to deal with this chronic infection for three months! Ugh.
