3 month old and coughing..

Bernice

My 3month old is getting sick. He has the cough... its a holiday today in canada so all clinics are closed.. what can i do to help my newborn?! I turned the heater and humidifier on.. i know i cant give medicines or lemon and honey... i just don’t want a small cough to turn into something big like a fever... any advice would be appreciated.. 😩

Thank you
