Tubes in ears?

ka

My son will be 2 next month and has had a number of ear infections that take a long time to heal. He’s been on antibiotics this time for 5 days and went for a check up and the inside of his little ear is still bright red. Doctor referred us to a Ear Nose Throat doctor next week. I’m nervous. I had tubes as a child but he seems so young to be put under for tubes. Anyone else have a child around his age that needs tubes or have them already with advise and If so what was the price range? NOT that it matters, if they say he needs them he will get them no matter what. Just curious. We have Blue Cross Blue Shield insurance.
