After hearing so much about this Dr's techniques from people at work I rented it off Net Flix. It was amazing to see how these little steps can help calm the baby down. Now let's just hope it works when my little girl comes..lol Totally would rec. watching it before your babies arrive.
Re: Watched Happiest Baby on the Block DVD
I haven't watched the DVD but my husband read the book and we used the techniques on our daughter. They really did work well in keeping her calm...now at 4 1/2 months we finally have "de-swaddled" her...she still likes the pacifier (which I know is the first thing they say to stop...but we'll follow her lead for now)....she's a great sleeper too...typically sleeps 10+ hours a night (and think the techniques helped her sleep 5-6 hours straight by the time she was 5 weeks).
She would sometimes break free from the swaddle sacks...but we did find the miracle blanket (you can find it on amazon.com) worked really well in keeping her arms down most nights...
Good luck with your little one...
