Reply to Our 9 month old won’t sleep without being rocked until she is in a deep sleep...

You're going to have to break the habit, which is probably going to involve a lot of crying, so first ask yourself if you are ready for that because it will only work if you are consistent. I'd suggest using a modified CIO method where you put her in her crib awake and then go in to comfort (only patting/shushing) at increasingly longer intervals. So go in after 5 mins, then 10 mins, then 15 mins, etc. You can max out at 20 mins and then just go in after 20 mins each time. It will not be easy the first few days, but eventually your LO will learn that this is how bedtime is now and she will be a much better self-soother.
