I have not read this book, but read 2 other similar ones, including Contented Baby and the Baby Whisperer. I feel that the Contented Baby is strict, but the Baby Whisperer is more flexible. It also addresses how to handle 猛長期. I started using this method when Katrina was 6 weeks old. I think it works quite well for us.
The Baby Whisperer is by Tracy Hogg, I also bought it from Page One.
i also buy the idea of this book.
but i think for newborns (0-2months) should not be too strict since they just arrived this world and have to adapt the human life. feed on demand is recommended, easier for baby to stay happy and grow fast, also easier for moms to build up the quantity of mama milk (frequent sucking).
after 2 months, quite some babies develop their eating mode already. training can be carried out at this time.
i used the method mentioned inside the book for my elder daughter. it worked. everybody says she is an easy girl to take care of.
now my boy is 4 months old. i started this method for him not long ago, and it works quite well. my boy is already used to this routine feeding-playing-sleeping mode. he does it everyday. easier for me.
