No, you may never see any symptoms. My next to the youngest grandson ended up being deaf from non healed ear infections.
That sounds odd but I don't know how else to put it.
He was always going to the doc just like any other newborn, you know how it is, there is a well baby check up every month or two and then if they are actually sick. He had been treated for ear infections a couple of times and taken all the antibiotics.
I had told my daughter I thought he couldn't hear. She thought he could. When he went into foster care the foster mom got them to send the baby to an ENT right away, he got tested. He didn't even respond to a bass drum being hit right behind his head.
The doc thought tubes might help, they often allow excess fluid to drain out and that allows the kids to hear. He went in to put the tubes in and found debris from past ear infections that had not been treated. This baby had been to the doc regularly and had taken meds a couple of times. The infection was just too deep or too resistant to that med.
So, my point is, even if the doc does not think there is an ear infection there may be infection deep inside that a medication may even miss. If the baby is acting like they are sick or in pain they need to see the doc.
With you keeping an eye on her you will notice the first time her fever goes up, that's when you need to call.
