Wow, that is alot of stuff to be done...I highly suggest getting a second and maybe third, opinion! Tonsils are a part of the body's first defense line...make sure it is an absolute neccesity to get them removed. Think about this, would you want to knock out an entire army just cause it was weak? No, you'd want to strenghten it first, right?.
Ear infections that come back and back aren't always best treated by tubes (sometimes, but not ALWAYS,... diet, environmental((smoking)) and the way your child handles blowing her nose, could make or break an upcoming ear infection.
There are great herbal preparations that help knock out sicknesses.
I use Herb Pharm ear oil.....it's garlic, mullien, and olive oil, you put in the ear(s) at the slighest sign of pain...within a couple days it'll be gone, there are also many immune system building preparations...check it out for your daughters sake, I know you trust your doctor, but I urge you to find some others doctor(s) to look over her as well.....
Surgery is a BIG decision and getting things REMOVED is BIGGER.... Probiotics, healthier food choices, little dairy, find out if there are any food allergies, garlic oil, all those things help and can maybe prevent surgery.... God bless you and I hope I've helped.
