DS is four months and for the last two weeks has had a bad cough but only at night. It wakes him up and one of us has been picking him up to get him upright and see if he can cough it out. I'm downstairs with him now - hes asleep but keeps coughing. Is there anything I can do?? He normally sleeps through but it's getting to the point I dread bedtime as I know I'll be awake at one am trying to help him with this. It's only at night it's so bad. I've put Vicks on his feet and snuffle babe on his chest and olbas oil on a bib in his cot.
