That is great news. IF you got her to stop in less than an hour the first day you tried it then there is great hope. Expect the next two days to be louder and more attempt to get your to "hear" her but if you all stay strong she will give in. In a sense it is the same as a leaving a child to CIO at naptime in the sense of you are on your own and responsible for your own happiness and some things are just not optional - in this case stop or rest - if she comes to the playroom and starts again send her back to try again and well as I said day one looks really positive to me. Good for you.
