Thankyou for your replies Viloet, Mommy2braylynn and Sqil30. I have been using a plug in vaporizer in his room which I think helps a bit. I think my son is finally asleep, but I expect he will wake up coughing soon. He has been waking several times every night. I think I am a bit calmer, but now I keep coughing. I have had a sore throat and headache for a couple of days but just put it down to being tired. I have just had a fantastic email from my husband. It included his flight details. he will be home on 17th January!! Only another 11 days to go. I can't explain how good it feels when I know my husband is on his way home, but it is one of the best feelings ever.
