DS has developed a bad cough over the weekend so l will keep him off school for 7 days. But what about his sister? Should I keep her off as well? DD is worried no one will play with her if they hear her brother is off with cough. And what happens after 7 days? If still coughing do I still keep him off? Advice says we are to keep 2 meters away from him but this is not really practical! So confused!
