I can tell you one thing that a sub pediatrician told me to do with the drops...put the drops in your bra and leave them there for the duration of the 7 days or whatever it is!!! The temp on the ear vs. the temp of the drops is around a 20 degree difference and when they are put into very sore upset ears, it really hurts for them!!!
I am in the exact same boat you are in. My son who is 16 mo old had tubes put in March 12 after 4-5 months straight of ear infections not clearing up. Now, since the tubes, he has had 2 nore infections. First time, a 10 day round of Augmentin that did nothing with the drops...and now the drops. I can't tell if they are working or not. But, I do have to say that in terms of putting them in his ears, 1) he is probably sick and tired of you putting stuff in his ears because they always hurt and 2) the meds really feel ouchy when they are cold. I also need to find out what the next step is, because I have no idea if we are just supposed to keep treating him for ear infections...(wasn't that what the tubes were for?)...or do we need to do something else?
Good luck to you.
