It took Matilda ages Kim. In fact, she still does that if I'm not serious. We were told that its 1 minute per age of child, and that for the first oh.... 5 days or so if you do it consistently... it would be a continuous thing of saying "NO" and putting them back on the spot. With Matilda, we had to actually lock her in the bathroom because she would bite us and fight us. But that was extreme!! We didn't want to do it, but it was pretty full on.
