Sleep training without CIO

Hi mama's. So I'm currently bedsharing with my 6mo old and looking to start transitioning him to his crib. He wakes up still every 2-3 hours to nurse, but I know at this point it's for comfort and not food. I really am not up for CIO, but it's time to start sleeping in our own beds. We have a nightly routine and he does nurse to sleep, at which point I put him in his crib and he will sleep in there for a couple hours, then when he wakes up I bring him in bed with me. How did you transition your LO to sleeping only in their crib? Any tips or tricks?
