Query: So many helpful tips!!

My daughter wasn't sleeping more than 1.5 hours in a row at 12 months old and I refused to let her cry it out. I got this book a month ago and now she's sleeping 3-4 hours in a row, big improvement! It takes a little time, it isn't instantaneous, but it really works. I'm looking forward to my daughter's sleep time to continue escalating :) I love this book because it offers so many different tips, there's something for everyone. You select the ones you feel comfortable with or that you feel would benefit your family and go for it! It's so simple to mix and match the tips, then remove/replace some if you feel they aren't helping. The book is a very quick and interesting read.
