For those that have had to re-sleep train due to regressions, teething, illness, etc etc, what was involved in the process? We haven't had to re-train yet but I want to be ready for when or if I do need to!
1. Did your LO cry as long the second (or third, etc) time around? Did it only take a day or two?
2. For those that did Ferber, did you stick to the same timed intervals as you did the first time? Or did you check earlier?
3. Did you do anything differently at all?
