I think I did at first but then as it started to change I left the band aid off more frequently. I think she had it on with cider vinegar over night then off in the morning getting ready for school. Then covered during school with plain band aid and off again after school and on weekends. Make sure you pull off a small piece of cotton wool to soak in the vinegar so that it only covers the wart and not the healthy skin. I made the mistake of using a whole cotton bud and her finger was a white pruned up mess the next morning. Good luck!

By the way, I don't know if I already updated in this thread but after it fell off I kept up the treatment for a while longer but could still see some roots. I didn't want it to grow back so took her to the dr who froze it for a second and it hadn't grown back.
