Oh i forgot i posted in here Sounds the same as DS he cleared up for a few days and then got a bad cough! Still no temp either. I ended up taking him to the doctors to check him out as i figured 3 weeks of it warrented a visit. Anyways he ended up having a swollen ear drum on the right side and tonisilitis. I thought he would have had a temp with that! anywho the doc said he was fighting it off well but it had gotten to the point where he needed a little help to rid of it.

If you think he may had a sore throat you can add alittle hunny in with some warm water and a splash of lemon juice and get him to have a few sips. Sounds like you are doing everything right though

Hope he is feeling better soon! This time of year alwasy sucks for these kinds of things xoxo
