You can do it in all the ways you mentioned.
While mimicking reflexology, please keep the intention with safety and security.
Whenever we mimic any medical treatment or healing modality, we can keep this intention.
You can always do different ways and experience VK differently.
You can even directly request VK please give the effects of 10 min oil massage to my daughter’s feet.
If you know the oil specify it. You can do this with safety and security intention
