My oldest son had to get them when he was 5yrs old. Simple procedure and worth it. You will see results shortly after the surgery. A lot of the problems that kids have from ear infections is from allergies that most of us suffer from. One thing to be careful of and the doctor may tell you is try to keep water out of their ears. My son had ear plugs that we got from the doctor when he went swimming. Hope this helps and good luck.
