I usually don't read this forum or dare to post, because after a post or two I get accused of advocating CIO and slink away a charred and smoldering husk. Which is so ridiculous because I would never recommend CIO and anyone who knows me finds that idea quite amusing.
This book saved my life. You might not find everything to your liking, but take what you can use and don't take what you can't use, obviously. No Cry Sleep Solution was really not any help for me. Both the books are pretty much what I already knew, but Sleep Lady's book gives plans, layouts, etc. There is A LOT of great value in the book: the importance of routines, how most children "who just need less sleep" are really not getting enough rest (something I always believed and have met great opposition over), etc. I like that there are age-appropriate chapters, so you don't have to sift through the whole book. I would not recommend using her method for a six-week-old, but then again to be honest I did not read that part. No Cry Sleep Solution also advises against letting your newborn learn only to fall asleep while nursing or rocking, so there are many similarities.
I also found NCSS to be less well-written and its cutesy tone annoying. Its information is good, though.
My son is 14 months tomorrow and went from waking every hour, or even more frequently, to sleeping four hour stretches at the worst and seven hours, then four, at the best. Not including naps! He needed to be nursed, or walked back to sleep, and it was all but impossible to put him down or slip away. Within only a few days he was so much better, and I no longer feared I would be featured on the news.
I did NOT torture him or make him feel unloved or interfere with his attachment in any way. I did not "just leave him in the crib to cry." I also think the author's comments on vomiting were taken out of context. I can think of several quotes that uphold her view that "the point is not to torture your child." She certainly says that you should pick your baby up if s/he needs it. She also says that while CIO will work (which is true), it isn't what she advocates or advises. The idea is to be gentle, and kind, loving and firm, which you have to do with children, starting in toddlerhood, anyway.
I think those who claim that any kind of sleep training, at any age, will do harm do not fully understand what Bowlby's attachment theory is really about. My guy was always a joy, always smiling, laughing, full of beans, but is now even happier during the day, which I wouldn't have thought possible, because he is getting better rest.
All kinds of other positive "side effects" emerged as well. My ds always startled so easily; he couldn't turn over in his sleep without waking up and crying. Now he moves all over the place in his crib, in his sleep. If he wakes, I go to him quickly and kiss him, and he sits back down and lies down and has barely woken at all. I did not have to force him to do this- it wasn't even my idea, it just happened. In fact, we were so amazed because it didn't seem we were doing anything and the improvement was immediate!!! I think we had fallen into a bad pattern of "rescuing" him from everything. It was making him very fussy and over-sensitive.
Some children *don't* sleep eventually. I know two in our family who sleep very little, wake very frequently, and are irritable all the time- they look tired; they are school-age. It is rare, but it does happen that a child needs help learning to sleep. I recognized my son in Dr Spock's description (and he never had a cry it out philosophy, btw) and *knew* it wasn't going to be outgrown, or that it would go away once he walked and tired himself out, etc. My daughter needed no help sleeping, ever. She was "easy."
The book is not really supportive of co-sleeping, though it does address the issues around it and it does give advice for getting your baby to sleep better even while in the family bed. The author makes clear her opinions on this stuff are not based on arbitrary thoughts but on her limited experience with people who have had problems and sought her help, and found the solution was through nightweaning, or no longer co-sleeping. She recommends nightweaning after a certain age if you are trying to get your baby to sleep all night, and if that's what you're trying to do, that makes sense. If your baby slept all night spontaneously, you probably wouldn't wake them to nurse them at one or two years, would you? I don't consider that an anti-breastfeeding philosophy. Different women will have different breastfeeding relationships with their children. There's no one right way.
I evaluated what I needed from my ds after a few days of the "sleep lady shuffle" and found I didn't need to go the whole way with it. My life has gone from total chaos to an actual rhythm. It's really nice. I bought the book two weeks ago today.
