I think the thought process is essentially good, getting into a routine and trying to get baby to sleep through the night and feed at regaular intervalss, I think her methods were wrong. I think it is ok to put baby in their own room (altho personally prefer to keep them with me for a period of time) I also think it is ok to put them down and walk away and perhaps even let them cry a little, but I do think you have to go back and sooth, you cant just leave them. Also, i thought it was good logic that fresh air makes baby tired, but didnt understand why you couldnt go for a walk or sit in the garden with a coffee instead of leaving them out there.
And, the affection aspect, well i couldnt reallunderstand the logic in that at all. We want to love our babies simple as that.
I also think her way instigates all these things far too early... you need to get used to baby and baby needs to get used to you before you can start a menaingful routine.
