My almost-3-year-old loves to put on her own shoes, but had trouble getting them on the right feet — until recently! I made her a red embroidery floss friendship bracelet (just like we did in 5th grade) and put it on her right ankle. Then I marked the bottoms of her right shoes with red nail polish.
Now she simply puts the shoe with the red dot on the foot with the red anklet and she no longer trips over backward shoes.
A bracelet on the right wrist would work too. To help reinforce the lesson, talk about "red" and "right" beginning with r, and paint a red "R" on the shoe.
Some of us still have a hard time remembering right and left.
