"Old school" wipes: damp washcloth in a plastic bag
Sharon's (dad's) hack is convenient, saves money, and minimizes paper waste:
This is a hack I’m borrowing from my dad, a 70’s single parent. Before the advent of disposable wipes, he would carry with him a damp washcloth in a plastic bag for wiping food off of faces, cleaning up sticky hands, random spills on clothing or even the occasional runny nose. When we went on vacation recently with my 22 month-old son, grandpa’s “old school wipes” were a godsend—I even added a squirt of antibacterial gel for good measure when the situation warranted it (like not having access to a soap and water to wash my own hands after a poopy diaper change). In retrospect, it was actually a pretty “green” alternative to wasting wipe after wipe, as I often find myself doing.
