H.L.
My 6.5 yr old does this as well. I usually help him, but only because I don't want him walking around smelling like poop and then ultimately he ends up with a sort of diaper rash!! We tried the flushable wipes but they clog up the toilets (I've had several plumbers say there is no such thing as a 'flushable' wipe that's ok for the household system!). My son doesn't necessarily get it on his hands but he just doesn't wipe well. My husband chastises me for doing it but I don't care. Like someone said, they all grow up!!
