What do you suggest if my child is one month old.lately she has got flu and cough. i don't want to go for antibiotics?

Confusing question: A one month old would not get antibiotics for a flu or a cough.If they had confirmed flu, the primary treatment is supportive. That consists of proper fluids and nutrition and comfort meds. Rarely infants would get a flu pneumonia and be given Tamiflu (oseltamivir) along with IV fluids.Without confirming your suspicion, you are just speculationg on the cause.If the kid has fever> 100.4, s/he should see a doc.
