We had been having an awful time getting our boys (2 & 3 years old) to sleep at night. I was almost in tears every night it was so stressful. Everyone was telling us that we had to let them "cry it out", put a lock on their door or at least a gate. I felt there had to be another way but I was skeptical of a "no cry" solution. I read through some parts (I'll admit it, I was desperate for answers so I didn't read the whole thing) and came up with a plan. IT WORKED THE FIRST NIGHT!! Since then there have been nights where the boys have tested limits and have not gone to sleep right away but I'm not getting 1/2 as upset as I had been. We're on the right track and we all feel (and sleep) so much better. I love this book!
