Cider vinegar for wart treatment 6 year old?

[Pachamama2017]

Hi there,
My 6 year old DD has had some form of wart on the sole of her foot (to the side) for about a month. I started using bazuka 3 weeks ago but after a week what was only a slightly raised wart became quite pronounced. Had a video call with doc who said looked more like corn/callus but to just keep using bazuka. 3 weeks later and no change apart from maybe slightly bigger still. Am now thinking of either discontinuing cream, for a week in the first instance, to see if that makes a difference and, failing an improvement, to try the cider vinegar route. However, I obviously don't want to exacerbate further. So has anyone tried? What was your experience?
Thanks in advance for any replies

Forget about the vinegar and go straight for duct tape. Not because I, a perfect internet stranger says so, but because the science says so.
Details on the science in these two short videos with all the references to the medical studies.

I have used it . It works, it is painless and quick.
Not sure about which duct tape. Here is the answer

I could never get duct tape to stay stuck on.

I used nail varnish on my DD's verruca. Bazuka and similar didn't touch it. Nail varnish made it dry up and I clipped away the dead skin every night. It was painless and just turned brown and shrivelled up to nothing. Took about 2-3 weeks.
