Thanks, Peachyclair, for clarifying. Nice to know we actually agree! But now that you've made it clear that you don't think personal experience is essential, I guess I can't really see what the objection to someone like GF is really. She has plenty of intimate experience of it, just not with her own biological baby.
blueshoes - it's not a science, you're quite right! But you say 'I am not sure what "firm guidance and wisdom" I could have imparted to my fussy baby, beyond letting her cry whilst waiting for b-feeds.'
This is the thing I'm talking about! I could use exactly those words about my own ds. Looking at him, he was being fed on demand, he was being put down to sleep in a quiet place every couple of hours, I was holding and cuddling him virtually 24/7, he was being kept clean and warm... I had absolutely no idea what else I could do for him. So I too said at the time 'I don't know what else I can do - this is just the way he is.' But at the same time, I just didn't think it was good for a baby to sleep as little as he did, to be as constantly whingey and grumpy and unsettled as he was - he just seemed miserable. It would never in a MILLION years have occurred to me to wake him up at a set time every morning, to start winding him down for the next nap 30-40 mins (instead of 10-15 mins) beforehand, to put in blackout blinds and fasten him in bed TIGHTLY with a sheet, to WAKE HIM UP(???!!) after a certain length of nap... All those things were totally unexpected to me, but she was spot on. They were transformative.
I certainly can't speak for your baby, but without a book like hers, I would have said that there was nothing to be done, that I was providing all his needs, and that I could only conclude that that was the kind of baby he was. But her totally counter-intuitive advice in fact met his needs much better than my more 'flexible' approach. Like you, I started off trusting that my baby knew his needs better than I - and it turned out that he had absolutely no idea, but some mad genius I'd never met knew exactly what he needed. :) I honestly would never EVER have believed her routines could work except that I tried them myself...
