I just finished reading The Sleepeasy Solution. Their tips are supposed to help your baby sleep through the night. I enjoyed it and learned some good things. It's hard to give a solid review until we actually try it/have a baby, but I'll let you know if it worked for us when that time comes. (We did try a few of the tricks on Copper, and his nighttime barking calmed down if that's an indicator lol).
I thought the main points made sense: Make the environment dark and quiet, stay on a routine, etc. Good stuff, a little redundant, but I'm guessing they thought the reader would skim it. Have you read it? Do you have another baby book you recommend?
