For the past few days my ds 5 cold has developed into a wheezing whistling cough, every inhale sounds like a whistle in his chest, GP is closed today, makes me nervous waiting another day as he is coughing non stop the closest walk in centre is open today should I take him there or to the a&e i wouldn't say he's struggling to breathe, but he is coughing every minute and I don't know if I can wait until tomorrow!!
