With this line of work I think it's good to have this option, my period got irregular recently which fucked up all my pre-bookings, so hopefully it will work! My period is usually mega heavy and painful anyway, I also have fever,, so I have to be in bed.
It has happened sometime I worked with a sponge during the first day when it is barely there (best to avoid imo, I will never do again), a friend of mine told me to use a baby wipe (which you wash and fold) and use it instead of the sponge, apparently more absorbent, any of you have tried this technique?
