I suspect the reason that most of those methods aren't mentioned much is because they're unlikely to work for folks with sleep-resisting babies. My babe is a relatively easy sleeper and none of that would've remotely worked for her. By the time people are desperate enough to consider CIO on here, they've already tried shushing and back patting, KWIM?
And frequent nursing is, in fact normal, natural, and healthy for young babies. As is cosleeping. When cosleeping/nursing doesn't work for whatever reason, then you have to try the more laborious methods, but there's no way I'm gonna get up and wear DD for a half hour while walking around the house (the only other method of getting her to sleep) if I can stick a boob in her mouth. Neither of us wakes fully to nurse.

I believe you about your son. Just feeling a little... irritable.

I cannot imagine how hard it is with a baby like that and another child making it even harder. 
DD1 was soooo easy- so easy that even I could tell it wasn't anything I did, kwim? DD2 is pretty hard sleep-wise. I keep thinking that once we're crawling, it will get better. Here's to that!
She just doesn't sleep, and if I over-nurse her (to get her to nurse when not hungry is a horrible struggle) she then vomits all over.
