DD2 has woken up with a constant cough. Based on the new guidelines I have to keep her at home for 7 days. Logistically I don't know how to do this. I don't work on a Friday so keeping her home isn't a problem, but her older sister is well and should be at school. I don't have any one else who can take her in to school so my only options are to take DD2 with me to drop off and pick up or to keep DD1 off too. As children, if they do get coronavirus, they're likely to be fine, but I don't know the health conditions of the other children or the parents/grandparents who will be at the school gate. Realistically, I do think DD2 just has a cough and cold.
Logistically, what am I supposed to do?
