Both!!
Toddlers and really bad diarrhea make for a very messy day. When there is so much coming out, that the diaper just can’t absorb it… like popping a water balloon all over my hands at every diaper change…. (but it ain’t water)….. you don’t blame the diaper, you get prepared. I grabbed some (lots) of paper towels, and changed on a wipeable surface. Be sure to have disinfecting wipes handy… And hire a babysitter to hold the baby while you take the world’s longest and most deserved shower.
