Oh dear, this topic becomes very very heated! I also read the book, and it said never leave a baby to cry if it is upset, just having a whinge/grizzle/ protest, in which case she says to give the baby a chance to self settle if they are whinging (about 5 mins from memory, depending on age), and then go in and pat/ shush/ etc to sleep. She also talks a lot about altering the routines to suit your babies needs, i didnt get the feel that it was ever intended to be rigid - she uses heaps of examples where the suggested routine has to be altered to suit the needs of the baby. I used the routines as a loose guideline, always responding to my child's individual needs first, and gently guiding them into a routine if and how it worked,depending on the needs of my baby. It was very 'gentle'. It seems to be a lot about predicting your childs needs, so they arent screaming from overtiredness or hunger, etc. Also about looking of causes for baby not to sleep - like getting too cold at night. Ahe suggests with a young baby to use more thinner, breathable blankets, so they can be easily removed or added to if bub is too cold or hot. Seems pretty sensible to me?! As in all things, if you follow your babies needs and take what works for you, i think that is the best way to go.
