What can we give if baby is having cough and flu? Thanks

Nursing as much as possible if you are breastfeeding. Cough may sometimes be due to back drip from flu. Cough and flu os usually a "package". Basically to clear the flu, i would use nasal drop or saline solution. Thereafter, let baby sleep slightly higher so that the mucus won't flow backwards. Wearing a pair of socks to keep the baby from further cold.
