I provide the wipes unless a child requires a specific brand and then that is up to the parent since I won't promise what I will use. I just have one container and use as needed. I removed a wipe before I start and two if I know there is a poop. Generally that is enough so I don't go back into the case except rarely.

I used to do separate ones and used the travel containers and filled them weekly from a master supply which I bought. That worked well since they were in their bin (empty square ice cream container) with their change mat and any cream the parent has supplied.
