That's what we have been doing around here. Not a ton of success yet, but we are still hopeful! Staging area is set with all the comforts of a bathroom right in the kitchen/dining area. Potty seat, baby doll on right next to potty seat, extra seating for those who choose to hang out with the one in training, books to pass the time, wipes and of course the reward that makes it all worth it in the end. M & M's.
Those are for me of course!
Sometimes a cash register helps pass the time too!
