What should I do

Hi everyone
I don't know if I am being unresnable but I take my grandchildren to school 3 mornings a week my daughter brings them to me and I take them to school but they are moving and she is changing her job which means I will have to go to the new house to pick them up as she won't need to come this way but the new house is 8 miles away so she wants me to go there pick them up and take them to school what would you do
