I should totally know this....DS is on an antibiotic for an ear infection. 10 day prescription, twice a day. Yesterday was the 10th day, but I have about 1/4 of the bottle (we got two bottles for the 10 days) left. Usually there's just a little bit left and I assume I measured a bit incorrectly. Am I supposed to finish the bottle or stop because he had 10 days already? TIA!
