This is my washer. Next to each dial is a little sticker by one of the settings. This means that my six-year-old and four-year-old can do their own laundry. Mostly. We’re still working on measuring the soap.
But they know how to load the machine, and after checking to make sure each dial is turned to the right sticker, to push the start button. Same with the dryer. A four-year-old might not remember to wash his clothes in cold water on the cotton cycle, but he can match the knob with the sticker.
