There is a great (short) book out there called On Becoming Babywise. It was a quick read with ideas that were easy and just made so much sense. We were recommended it by some friends with our second baby, and she slept through the night around 5 or 6 weeks (at least 6 hrs). It helped with so many other things also, our lives were a lot easier than they had been with our first child. It talked about making a schedule that works for you. Feed your child strickly on this schedule, and don't feed them to put them to sleep, it makes them depentant on this. We fed our daughter every couple hours at first, even if we had to wake her, and even as a new born attempted to keep her awake for a few minutes. Then we would just lay her into her bed. As the weeks went on, we would up the time line, because we had to keep waking her. The book also suggests not using monitors at night. It said you will hear your baby if there is a problem. Not everyone may be comfortable with this, but we did it, and our duaghter seemed to learn that crying was not the way to get everyone in the house to jump up. If on the occasion she woke a few minutes before her feeding, she just layed there quietly. According to my doctor, she would cry if she was uncomfortable because she needed to eat. My doctor also said that it was fine that she was going so long at night (we had a full 9 hrs by 2 1/2 months. The book also explained that many time, babies that are still waking up throughout the night when they are 6 mo. or so are doing so out of habit. They may be hungry, but its because they are not getting enough during the day and evening, or they may not be hungry, just kind of programmed to wake up at certain times. Everyone finds different things that work, but this helped us. Good luck.
