Re: Transitioning sleep cycles
we used a white noise machine and a crib thing that lit up and played for a little while.
we were also still swaddling until 9 months, which helped.
If you'd like to break the rocking routine, but not use CIO, I'd recommend laying him down in his crib and just patting his back, singing - whatever calms your kid.
