My DDs have yet another chest infection but this time as soon as they lie down they go into sparodic coughing fits that last hours. Neither have slept much in the last 24 hrs and are both tired and feeling sorry for themselves. I'm using over the counter cough medicine but its doing nothing but i don't want to drag them to the docs just to be told its a winter bug and all parents worry yet again. Any suggestions on how to ease the coughing fits so the poor babies can get some sleep? Thanks
