Wad should i use or wad to do to make my 5mth old baby breathe better? He has flu. Seems to get blocked when slping in aircon room. Use vicks vapo rub apply on baby's chest?

Please bring baby to see doctor and get the correct meds to clear the airway. If baby is sleeping in the cot, you can prop baby up or elevate the cot/bed. You can use baby safe vapour balm to apply on chest and sole but may not clear the airway effectively. Possible to use fan instead of air con?
