To help teach my son, I made a visual game of it so he would nderstand the concept. I filled a paper cup with shaving cream and gave him colored napkins. He had to wipe all the shaving cream out of the cup using as many napkins and as much time as needed. If any cream showed on the colored napkin, that meant that the cup was still dirty. While he had fun doing this task, we then related it to wiping in the bathroom. If the tissue is dirty, then you have to keep cleaning! He loved using the Kandoo wipes too though we taught him to only use 1-2 wet wipes and tp the rest of the time. Now he gets the concept.....if only I could get him to care about it ;)
