I would suggest you take a tablet of cetirizine
once a day for 5 days. It might help relieve symptoms of runny nose and blocked ears. Steam inhalation 4- 5 times a day might help you tremendously. Have only warm fluids to drink; be it warm water, milk, green tea etc.
I would also advise both of you to visit a physician if do not find any symptomatic relief in 2 days. You might require antibiotics if you have persistent cough
, greenish/blood stained phlegm, fever
Hope this helps.
