I (and quite a few of my friends) totally love "Toilet Training in Less Than A Day" by Azrin. Works starting at 20 months. My daughter was 25 months and my boys were 27 months and 31 months. The last was pretty insistent he wasn't going to play the game. :) He knew what to do at 22 months, just didn't want to.
I used my blender. I also had a little hand grinder for when we were out.
GL with both!
