Dr prescribed amoxcillin 250mg/5ml , 2x a day, 5 ml for ear infection, child is 43 lbs. still having ear pain. doc said this dose is correct? but doesnt sound right?

Usually more mg's: Amoxicillin orally taken for an ear infection can be done into 3 doses each day. First dose is with breakfast, around 6:00 to 9:00 a.m. Third dose is before bedtime, around 8:00 to 10:00 p.m. Middle dose is about halfway in between. In an ear infection situation, we don't worry too much about exactness. A common dose is 250mg three times a day or 500mg twice a day.
