We got tubes put in our son's ears when he was about 1 1/2... I understand the fears and concerns you are having. After 8 infections in 3 1/2 months, we were also told that tubes may be a good thing to consider.
We met with an ENT (Dr. Snyder in Londonderry - I highly recommend him). They did a hearing test and since his hearing had not been effected, Dr. Snyder was very informative, but did not pressure us in either direction. We did not want our son to be on antibiotics as much as he had, so we decided to do the procedure. And I am so glad we did!
I'll be honest. The hardest part was the morning of the surgery. It is heart-breaking to watch your child have anesthesia and they are definitely frazzled when they come out of anesthesia... That being said, it's definitely worth it though. Our son was back to his fun-loving self later that same day! He didn't get a single ear infection the entire time he had tubes, and even if he would've gotten one, they have you put the drops in their ears for 4 days (no antibiotics). My son's tubes fell out earlier than they were expected to (but that's okay). The ENT checked him when they came out, and we have not had tubes for a year now... and he's only gotten two infections since the tubes fell out.
I'm very glad we made the decision and I was very pleased with our experience. As far as the maintenance.. the first week was a bit challenging getting the ear plugs in for bath time, etc, but after 2 weeks or so, he was reminding us when we forgot. They also sell a neat swim band for kids that need to wear ear plugs... My son loved wearing that in the pool over the summer.
