Prepare the bathroom or kitchen sink area with a step stool (if necessary for your child), hand towel and hand soap. Take a photo of the sink area, and make sure the towel, soap and faucet appear in the image.
Have your child get close to the sink as if he's preparing to wash his hands. Click a photo to capture an image of your child near the sink.
Turn the water on to an acceptable, warm temperature. Position your child so his hands are under the running water. Take a picture.
Have your child push down on the hand soap dispenser with his dominant hand as soap drips into the palm of the other hand. Take a picture.
Instruct your child to rub his hands together over and under the tops of each hand. Have him sing the alphabet song. If he doesn't know the song, you sing it. While your child is rubbing soap around his hands, take a picture.
Have your child rinse his hands under the running water after you finish singing the alphabet song. Take a picture.
Instruct your child to turn off the water if he can understand simple commands; otherwise, you turn the water off. Ask your child to use the towel to wipe his hands. Take a picture.
Upload the images from your camera to a computer. Choose the best images from each stage of the hand-washing process, from the opening scene of the sink area to the image of your child drying his hands with a towel.
Print each image to a size of 4 inches by 6 inches, or something comparable. It isn't necessary to print the image to fill an entire 8 1/2-by-11-inch sheet of paper. Allow each image to have its own page. Keep in mind you will make a booklet out of the pages, so make sure all the images are oriented consistently for a book. For example, if your pages will be vertical, make sure all images can be viewed properly holding all the pages vertically.
Write a description of each scene under each picture using simple phrases. For example: "Chris wets his hands" and "Chris uses soap."
Laminate each page if you own a laminating machine. Allow your laminating machine to warm up. Put each sheet of paper in its own laminating sleeve. Run each sleeve through the laminating machine to seal it.
Use a three-hole punch on the side of each page. Place the pages within a three-ring binder or connect the pages with yarn. Create a cover page, if you'd like, with a title, such as "Chris Washes His Hands."
Sit down with your child and go over each page of the book. Use an excited tone, and make reading the booklet a fun event.
Ask your child if he's ready to try out the booklet. Keep the booklet at the side of the sink and have your child imitate each picture as you read the description and turn the page. Praise your child as he completes each step.
Accompany your child each time he has to wash his hands, and follow the procedure of reading the book as he completes each step. Continue to do this until your child can wash his hands on his own. Keep the book around as reference if your child ever needs to revisit the steps down the road.
