My 21 month old has had a very snotty nose since Thursday, I kept him off nursery Friday as he gained a cough to go with it but the cough only appears when he's going to sleep or just waking up, when he lies down I suppose. No temperature, eating fine and ok in himself. Would you get a test? I really do think it's a cold it's the cough that's making me worry, does anyone know if the cough is worse when lying down with coronavirus?
