I really need some advice!!

My 2 year old had around 10 ear infections from the month before he turned 1 for the next year.

He went to an ENT and he said he should be growing out of it and it was almost summer so he didn’t do anything.

Well now that it’s colder he already has an ear infection and is back on the antibiotics he has been on about 5 or 6 times and he is continuing to tell me his ear hurts.

I don’t know what to do. Every time I take him in if I go to early his dr says his ears are “just red and not bulging” and to give it time but it ALWAYS turns into an infection. I have an 8 week old now and it’s so difficult when he has an ear infection and caring for her also

Has anyone else been through this? What should I do?
