Hi - I have a 5 month old who has had a persistent cough for the last 6 weeks I have been to the doctor but because he is gone in himself and no temp they basically told me to stop wasting their time. He's eating, drinking, sleeping, weeing, pooing and smiling and no temp, few sneezes and a bit of snot but not much, but I don't think he should have a cough for so long?! It sounds likes there is mucus there but sometimes sounds dry, he also has fits of coughing in the night which aren't very nice but also in the day too, it doesn't seem to bother him but I'd like to get to the bottom of it. Any ideas?!
