My wife and I have tried everything with our 2 week old boy, with varying degrees of success.
Some days swaddling him works, other days soothing him seems to work, leaving him be to cry it out for 5 mins works on other days and other things the worm for the rest of the time. It's mind-bogglingly frustrating!
What we realise now is that BW is changing every day, so while he might be appearing to begin eating/sleeping to a pattern for a few days, it will suddenly change, because he is changing. We keep thinking we're doing something wrong, but we both now think that he is constantly changing and developing, and so our approach has to develop too. We have to he flexible to his needs, and not his to our wants.
He definitely seems more happy when he's latched on, but this means Linda isn't getting a good nights sleep, however we've just purchased a babybay/crib that fixes to the side of our bed and that is working well (meaning we don't have to transfer BW to a moses basket). Lnida simply gives him his late night feed then, after a few moments of settling, slides him across into the crib (into which we've placed a pre-warmed mummy-scented muslin as a thin pillow!).
Actually night times are better than days at the moment - he will go off at night for 2-3 hours at a time between feeds, but the past few days he just wont be put down! It's all over the place, but we keep telling ourselves it will get better, that he just needs to be shown love :)
We're trying to consider the idea that he doesn't want as much sleep as some other babies - he's healthy, gaining weight and looks ok, so we're currently trying more stimulation (cuddles, lullabies, patting/rubbing etc) before putting him down.
Good luck all :)
