I live with my mum and I have school aged siblings. One of them had a cough the other day and the school needed him to have a test, it came back negative. My 4 week old has now caught it, he's been coughing since he woke up yesterday morning. I'm not sure if I should worry as it seems like a chesty cough and he seems to cough lots and then he's ok for a while then he coughs again
. He seems ok otherwise though as he's not got a fever and he's feeding fine and having plenty of wet nappies etc.
Would you worry about this?
