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

I used to give my child Tempra for flu (3x a day, 0.6 - 1.0ML depending on her age) for continuous 3 days. I'm not sure if it's available in SG though. For cough, we've proven and tested that pure oregano extract does the trick! (Pick 2-3 oregano leaves ; wash thoroughly; put on top of steamed or cooked rice making it moist and retaining the extract rather than boiling it directly in water; leave it there for 5-8 mins; extract leaves juice using your clean hands to feeding spoon; feed directly to baby before nursing. This makes her throw up the phlegm due to the pungent taste or will poop them (happened when she grew up and liked oregano already).
