My 5 year old has had a cough and cold for about 5 days. The past three nights she has struggled to get to sleep due to coughing. Most of the nights she has had a good couple of hours periods of coughing almost constantly. She was prescribed antibiotics for an ear infection yesterday and has started those. She has been trying to get to sleep coughing for the past 2.5 hours solidly. She is exhausted. I have tried tixylix, manuka honey, honey and lemon, olbas oil in hot water in her bedroom and nothing is working. She has been sick three times (mucus) through coughing and I’m not sure how to make her more comfortable. Any tips please?
