Skorpy, can you run the hot water in the bathroom with all the doors and windows shut, turn the water off then take him in there. Apparently the steam is really good for decogestion. Just check with your GP, but it will get things moving so he can breathe, the poor little thing.
Came back from the Doctors earlier today and then just came on to read this,and you have said the exactly the same thing as what the Doctor advised me.

I will give it a go,she also gave me some nose drops,but it is just sterilized water,see how that gos.
