So we have used taking cara babies two times. I have a 21 month old and a 6 month old. The first time we used it for my oldest daughter it worked like a charm. The first few weeks of course were difficult trying to help Atley to learn to sleep. BUT it worked like a charm. Every week we were able to get another hour. She is now 21 months and sleeps 12-13 hours a night. I didn’t know if that was a fluke, but when we had our other daughter Avery we were game to try it again. I rewatched the course and we started again. I didn’t know if Atley had just been a great sleeper or what. BUT It worked great again! She is now 6 months and she sleeps 12-13 hours a night. We are so grateful to taking cara babies and we recommend the class to all expectant mothers!! (As a FNP I run into quite a few expectant mothers and feel truly confident in recommending this class)!
