Query: worked for my older kid

I bought this book when my first child was 2 and firmly entrenched in her own bad sleep patterns. I started in the infant section and implemented all the suggestions that I could; bedtime routine, focal feeding (bedtime snack), etc and moved on from there. It took longer than the book suggested, but it worked. I have since used it from day one on my second child and have reapplied the priciples when the older child began waking in the night and wanting to crawl into bed with us. It DOES NOT involve "crying it out", but if you're a whimp you'll never see it through.
