My poor little man has mild croup

 I don't know what to do for him :( he has mild croup the doctor says listening to his cough - but it isn't severe because he isn't making a noise when he breathes in or out and his temp is stable :/ he's so unsettled and when he coughs it's hurting him :( I'm keeping him as comfortable as I can, paracetamol and iburprofen (advised by doctor) but he just doesn't seem to be getting better :( he's only 5 month old :(
