I have read her book over and over again and tried to do what she said over and over again and the more i tried, the more frustrated I got when it did not work. I think she puts unrealistic expectations on little babies. Newborns cant possibly be trained, and if kids don't want to sleep 3 hours straight they wont. Mine never did. I found it more rewarding to go with what my nurse said at all my daughters monthly checkups. Books make you feel too guilty.
