I have been reading the book and I'm thinking about giving it a try. I was wondering if anyone has used it, and if so did you have success with it? Anything that you would do different? Any information that you have would be great.
I'll probably get flamed for this, but yes, I used BabyWise, and I highly recommend a loose version of it. Some people say it tells you to starve your child, etc, but most of those people didn't make it past the first chapter.
I put DD on a loose version of BabyWise at 6weeks because she had her days and nights mixed up. By 8weeks she was STTN. Having her STTN was not the reason why I read BabyWise, it just happened to be a product of it. I simply used it as a way to get her on some sort of a schedule so I could function.
She was already on a 3 hour feeding schedule, so that did not change when I started BabyWise. The only thing that BabyWise really taught me was to try giving a paci instead of a bottle at one night feeding. I quickly realized that I was actually waking DD up to feed, when all she really wanted was her paci. Over 2 weeks, I was able to drop both middle of the night feedings so she would get her last bottle at 10p and her first at 5a. It also really helped DD know what to expect during the day regarding naps, etc. and I didn't feel so unorganized as a new mom. Good luck!
