I think a little bribery can go a long way in certain situations LOL. WHen DS needed a little motivation to keep going in the beginning, I'd give him hand stamps, stickers, etc. to help him be more excited about using the potty. It didn't last more than a week or two and really gave the extra boost we needed to continue on. What I mean is, a little incentive can be useful, and won't necessarily make her always expect rewards for using the potty, kwim?
