P.P.
M.,
There are people who will tell you not to put tubes in and people who will tell you it's the best thing they ever did. I was also torn when my son had 6 double-ear infections in 5 months, and I heard advice from both sides.
The issue was, he'd be on the antibiotics which would clear up the infection, but it did nothing for draining the fluid in his ears. So as soon as the antibiotics were done, the infection would start all over again in that stagnant fluid. I certainly didn't want my son on antibiotics for months on end, since there will surely come a time when he needs them for something more serious than an ear infection, and I certainly don't want him to "immune" to the antibiotics by that time! So we did choose to have tubes put in.
It was literally 10 minutes between when they took him out of my arms and when they came out to get us when they were done. It was so quick!
My suggestion to you is this: if you decide to have it done, make sure a PEDIATRIC otoroncologist performs the surgery, and a PEDIATRIC anesthesiologist is on-hand to administer the anesthesia. I'm not knocking those doctors who treat all ages, I just think it will make you as the parent feel more secure knowing that your child is in the hands of people who work with child-size surgeries and medications every single day. (I can't say enough about Children's Memorial. If there's one near you, go there.)
Good luck to you! I know it's a tough decision!
