5 year old DS woke up a few minutes after falling asleep and has been up coughing since. Not in a distressed way, he's sat up reading, but the cough won't stop long enough for him to be able to sleep.
I've tried steam, hot tea, honey, throat sweets, nose spray, propping him up...
This has never happened before! What more can I do? He's happy enough bless him but he's going to be exhausted tomorrow if he doesn't fall asleep soon!
