My ds is 7 mo old and has suffered an awful lot with one thing and another lately. On Thursday of last week he started coughing, the cough seems to be okay during the day and he seems to be able to handle it as it's not a lot. However at night it's a different story. He doesn't sleep for more than 2 hrs at a time and then wakes up coughing and coughing, he coughs until he goes blue sometime, or until he vomits. Then he screams and screams for anywhere up to 2 hrs. I've tried Trixylix, calpol - but am at a loss now as we've had no sleep for a good couple of weeks now and it's only getting worse:(
