Sleepless night 😩😳😴

My sweet babe is 6 months old and will not sleep in her crib. She will just cry and cry. She will sleep in there doe nap time but not at night. We have her in with us at night an she’ll sleep all night long. I know theres a lot of people that say it’s so dangerous and horrible but that is the only way she will sleep and she will sleep through the night. And my husband and I are such kite sleepers. We have a noise machine in her room, we’ve slept on her sheets to get our smell on them, I have a diffuser with lavender oil, we have a night time routine and I just don’t know what to do. But any suggestions on what I can do/try?
