In the 1980's Velcro shoes were totally cool, but my mom wouldn't let me get them until I could tie my shoes.
I remember practicing the bunny ear method on my rainbow Peaks and finally figured it out after several attempts.
To see a product that might help your tot tie or sew in the future,
Maple Landmark makes nifty lil lacing helpers that set tots up for future tying — Lace-A-Shapes are solid wood painted animal shapes that help kids work on their hand-eye-coordination while pulling laces through the monkey, fish, teddy and butterfly. The set ($26) includes all four shapes.
