I have a 7 week old, and I've spent the last week pondering this question. I read tons of books with my first, and it didn't matter, she still woke up until I weaned her.
I honestly think it has more to do with the kid than with the method --though parenting philosophy will for sure impact this. My 7 week old is sleeping much better than my daughter ever did and I have done nothing differently. I thought about putting him on a strict schedule and not doing demand feeding, but 7 weeks is just so young, and I really do believe in the 4th trimester. We have a schedule, but he does like to nibble in between feeds, and I'm OK with that. If he needs to be comforted and he wants my boob, so be it. I also thought of doing the putting him down almost awake from the get go --using the baby whisperer method-- but it strikes me as totally ignoring the 4th trimester. Most methods that are really strict in schedule seem to ignore the 4th trimester.
In any case, a few things I do plan on doing differently: around the 12 week growth spurt, I am going to be very careful about responding too quickly to the off-schedule night wakings. Babies usually get into a rhythm of waking at the same time every night, so when they start waking at other times, it's a good sign that they are having a growth spurt. My plan is to feed him when he wakes, but if he shows no real interest in food and doesn't do a full feeding, the next night I'm going to try to ignore it and see if my hubby can just get him back to sleep, so we don't cultivate habits.
I'm also practicing putting him to sleep by patting him so that I have at least two methods of helping him to self-sooth enough to fall asleep. That way I can not feed him at off wakings. I have also moved him into his own room so that I will only respond when he really needs it.
I have no idea if it will work or not, but I honestly am just going to listen to my gut and go from there. If my baby isn't sleeping 8 hours anytime soon, I'm not going to worry about it. They are only babies for such a short period, and soon they will be off to college. I had thought I wanted sleep, but when I really thought about it, I want my newborn to sleep on my chest from time to time. I want to comfort him in that way. It seems right to me---at least for the first 11 weeks. I also don't think it's normal or natural for them to sleep 8 hours at an early age, I think they can be conditioned to do that, but it isn't normal --thus why most babies don't do it.
