My 4 month baby has cold since last 9 days, basically her nose is stuffed, I was using nasoclear drops but she still had colds and she is taking feed, playing sleeping everything normal just disturbed with cold. I consulted her pediatrician he prescribed kefpod 100, alerid, hatric. Otrivin drops I am concerned about this antibiotic, is it necessary to give antibiotic to a 4 month baby? Please help. Before this I went to another doctor on her 5th day of cold he gave synclar (antibiotic), maxtra for 3 days I used but no improvement then I went to see that doctor above. What should I do? Please reply.
