As I mentioned in my post about Palmer's Schedule: 0 - 3 months, we took most of our cues from her natural circadian rhythms in order to determine her schedule moving forward. We were fortunate from the beginning because she never confused her days and nights and started sleeping through the night around seven weeks. I remember this vividly because we took her on her first trip to Chicago when she was just shy of two months and she slept the entire night each day we were there, I'm sure due in large part to the time change.
I truly believe sleep in the early days is luck of the draw. Each baby is different - some are more inclined to sleep than others and there's no quick fix. Hopefully, over time, that can be corrected through patience, structure and routine but at this stage physical touch and ensuring the baby feels secure and comforted far outweigh schedules.
