Ear infection

is there any home treatment for ear infection?
My child is 3 years old and goes to kindergarten since September ( never been to daycare before). During the past 2 months she had a series of colds and several bouts of fever and LOTS of mucus, and tonight (after being weak and irritable for the past few days) she went to bed early, lamenting an earache.

Is there anything I can do to help her? How d I treat her symptoms? DO I need to see a doctor or can I just wait for the ear infection to run its course?

Thanks for advice Tweet
