The child is two years old, and has suffered earache three times, the first two times she was given penicillin.and the third time Bactrim (a sulpha drug). What would be a good homeopathic remedy? She is slim, loves sweets, is prone to colds with a great deal of mucus, and has had a bad bout of flu, does not care for margarine ( we do not give her butter or cow's milk products because her mother is a juvenile diabetic and it has been found that giving cow's milk to children increases the risk of getting diabetes). Thank you.
