A natural antibiotic that I have used with all 3 of my children and many nieces and nephews is GARLIC OIL CAPSULES. Just poke a hole in end, squeeze out on spoon, wave match under spoon 2 or 3 times, pour into ear slowly, place cotton ball in ear, go to bed. Should be better next morning if really bad may need to repeat next eve or two. Has worked every time.
