Baby not eating well while on antibiotics

April

My son got a ear infection and has been on antibiotics for about two or three days now. The past two days he refuses to eat or drink water.. he usually eats 6 times a day (5-7 ounces) is only taking about 3 ounces every 4-6 hours. He seems to feeling better except for not eating as much. Anybody experienced this while their child was on antibiotics and their appetite eventually came back?
