my 2 year old started a very sudden heavy cough yesterday, it is worse than I have heard before and seems to be causing pain, he has been up most of the night and has a temp of 37.6. Just seems strange was so sudden, has not had a cold just drooling a lot and a now a runny nose. NHS 24 advised taking him to see doc at hospital in middle night wed night when it started as he seemed to wake struggling for breath and making funny noises, he didnt really say or do anything just said dont think anything to worry about, now it just sounds like a nasty chesty cough. Off food aswell.
