I'm so sorry your little one is sick, and I personally know just how grouchy ear infections can make little ones. My Gracie had so many between the age of 3 and 4 that her ENT (ear, nose, throat doc) ended up removing her adenoids and tonsils and then...poof... not one infection since then.
First of all...the high temp is really nothing huge to worry about if you know what is causing the temperature in the first place. Little kids can run up to a 106 degree temp for five days before doctors really get concerned. You're right to keep her on motrin, not tylenol, so definitely keep that up. If you really can't get her to drink it, mix it with a little juice and have her drink it that way.
It worked best for me to keep Gracie propped up on two pillows when I put her down to sleep (almost like she's sitting up) because fluid tends to collect in the ear canal and cause more pressure when they are laying down. Sitting up keeps the fluid draining down the back of her throat. MOre often than not, I would end up letting her sleep in the recliner when her ears were bothering her really badly.
I was also told to limit Gracie's dairy intake while she had an active infection...I don't really remember why though...
Hmmm...what else...
Obviously, try to keep water out of it in the bath. But I was also told not to ever use Q-tips in your kiddo's ears. If you ever need to clean them out, only use a cotton ball. Q-tips weilding adults only tend to push the ear wax further into the ear, instead of getting it out.
My ENT also said never to let a regular physician do an "ear wash" on your child. (Gracie had them done pretty often after infections until I was told this) This is where they take a water pic and flush out the ear and scrape away any residual wax. Not fun at all for little kids.
I know this really stinks and I'm sorry your little girl doesn't feel good, but count yourself lucky that this is your first one. If she has repeat infections throughout the year I really recommend getting a referral to an ENT yourself, because that made all the difference in the world for us. Hopefully you'll never get to that point, though. Good luck!
