I only wish we'd gotten this sooner! Our 9 month old didn't take long to adjust to sleep training and now she sleeps 10-12 hours straight every night! We've just done nap training too and her naps (and daytimes) are so much better! It's a simple idea, but honestly I loved the videos because Cara's soothing tone and explanations made me feel more relaxed and empowered to do this with my daughter!
