Ds (3.5 ) is coughing like mad, it's really sore , and keeping him awake as it's roughly every couple if minutes. I've given him som cough medicine and sone calpol but neither seem to be having any affect. Us there anything I can do/give him to ease it a wee bit. The poor soul is wiped out with it, and I 'm worried if he doesn't get some sleep he's going to be really poorly, as he isn't eating much at the moment either
