OP I was told 24hrs without vomiting or the runs for kinder & school, so I always allowed the 1 day gap... It's a giant PITA but Atleast then your not worrying she's passing something on to someone else?

Will come back in tomorrow, got to have DD2 at kinder by 8:30 then DD1 to school at 9 with the 15min drive in between and dragging DD1 out from seeing her old teachers
