I think your daughter has been through a lot. She has been dosed with a quite a lot of medicines in a short time and it is good that she has come back to normal. Actually, viral infections do not respond to antibiotics. But doctors give them to prevent secondary infections. Quite often they do some damage, temporarily to the gastro-intestinal system. Give her what we call cooling foods - tender coconut water, curds set for six hour and food without any spices. Distract her with toys and music for some time and let her sleep. Give her body time to heal itself. Do not get agitated when she cries, but soothe her with your affection and calmness.
