D.P.
I am there--or was there til very recently. I have an awesome tip for you that was passed on to me:
What helped was having my son use the belt from his robe to practice.
With the robe on and we also removed the belt and had him tie it around his thigh(s). The belt is bigger, easier to see what's going on when you tie...he got the hang of doing the shoes pretty quickly after the robe belt practice.
Oh! At 8, he has now deemed velcro shoes "uncool" so that was a big part of his motivation! But he still jams his feet into the already-tied sneakers sometimes. Sigh.
