kindly give nasal saline drops (nasoclear /nasivion s)every three hourly and since it is a salt water/saline water it does not have any side effects and can be given again and again for nasal blockage and respiratory cough.
it will dissolve mucus in nose and throat.
for fever and pain give paracetamol.
anti-cold medicines at thxis age have got side effects so can be given only after medical consultation.
