For those of you that still do night feedings while sleep training, did you put your LO back in crib after they were done and just let them CIO back to sleep again?

My LO used to sleep thrust night without feeding, but recently before we started sleep training, she started waking up around 4am for a feeding again. So when she cried at 4am today I went in to feed her, but she immediately started crying when I put her back in the crib. (Still crying right now *sob*).

Also, LO is 7.5 months now, maybe it's time to night wean as well?
