Yes it is normal to get them replaced, please don't wait to long to get them replaced as it can cause long term damage. My son was forever getting infections, but it was a bit late for one ear, and now he is profoundly deaf in one ear. all the best.
Thanks. I just found out he's having issues again. I went to the E,N,&T specialist Wednesday as his primary care Dr said she couldn't tell if the tubes were intact &/or functioning. He is already scheduled for surgery.. I just thought it was weird he needed another set of tubes so soon..
I had tubes in my ears twice but I don't recall the length of time between them.
