Z.A.
Bacterial meningitis, especially in the very young, is deadly. Of course, it can merely cause brain damage and/or permanent nerve damage. Also, the test to see if one has it & what type it is once a person is suspected of having it, is also dangerous and extremely painful(withdrawing fluid from the spinal chord).
I am not telling you what to do, merely to take it very very seriously.
I WOULD highly recommend a second opinion not because the process sounds like a Pain In the A** (after you've just been through months of PIA's and this is on more), but because 1) it sounds like you aren't happy with your current pediatrician, and 2) because the only people I know who CONSISTENTLY get 2nd (and 3rd & 4th) opinions are Dr.s themselves. :)
Where I would also highly recommend looking for a pediatrician is Children's Hospital itself. Especially since you're looking at the possibility of at least one surgery there (and they're the BEST, so good on you), it would make it much easier on you to already have a friend in your corner, so to speak...as well as the logistics issue, of just being able to walk across the hall for just about everything you need.
http://www.seattlechildrens.org/ has a "physician finder" section of their website. Personally I always prefer calling, & talking to a person, so I can explain my situation. ###-###-####...I think option "2" is for help finding the right doctor or group.
Good Luck!!!
