Edward I'm with you on your post, although I haven't trawled through all 12 pages. I don't know any mother (or father for that matter) who would do something if they thought their baby was genuinely distressed and upset for any length of time. There is a big difference between a baby having a wee wind down mump and a baby screaming and gaining momentum as Angeldog's article outlines with different baby types.
I don't agree with leaving a baby screaming alone distressed for lengths of time, but I can, as am sure we all can, tell the difference between our babies cries and CC has worked for us (at 8 months).
I did try previously and DS was very upset and it was obvious to me that he was not going to wind down and sleep. I therefore, did not leave him crying and stopped the process. I tried again last week and this time it was totally different. Maybe DS was just that bit older and more confident, but I could tell the difference and on the third night of cc he slept from 7:15pm to 6:25am with no issues at all having previously always woken 3 or 4 times in the night.
When doing the cc, he would cry for a few minutes (but not in any real distressed way), and would then mump until he went to sleep, with me going in to reassure him at reasonable intervals.
From angeldogs article, CC is not going to work for everyone, but you can tell when it is and isn't going to work. Maybe some posters have had children who cry and build up tension and so therefore cc did not work for them and they think that other mum's are leaving their children crying at the intenstity that their children were? Just a theory.
Everyone needs to do what is best for their individual baby and that they are comfortable with.
