Girls, I had a temperature for two days, not more than 38. It's gone today, but now there's a cough when the child plays, he doesn't cough at all, just a few times and that's it. I lie down and cough not often either, but very badly, like it's choking him. We have a bit of a runny nose and upper teeth are coming out. How can we ease his cough during sleep? Has anyone experienced this before? We can only call a doctor tomorrow, it's the weekend and there's no on-call doctor in the polyclinic.
