A.T.
Don't worry! My family has a genetic tendency to have under developed ear tubes. Both of my brothers and 2 nieces and 1 nephew needed ear tubes. One niece was incorrectly diagnosed as ADD and put on Ritalin for a year when she really was deaf in one ear and about 50% in the other ear - she didn't talk much - didn't say the ABC's and said "Ha" instead of "Hi" kinda like a deaf person who has learned to speak. Anyway - they finally got a decent pediatrician who took her off the Ritalin ( it made her a zombie) and had tubes put in her ears and she also needed to have her adenoids (sp?) removed. Within 2 months she was reading and writing and skipped a grade because she could finally hear what the teacher was saying!
The only real precaution with ear tubes is that they can't put their head under water. Ear drums don't have pain nerves so that's why she didn't act uncomfortable.
Getting a 2nd opinion is always a good idea. Tubes sound scary - but it's very simply done and can make a big difference.
Good luck!!
