Sleep issues

So we co- sleep. And my daughter nurses to sleep. I'm basically her pacifier. I know this is a big no no but I truly did try everything and that was just what worked for us. Now I have been able to get her to sleep with just foot massages, or back tickles, and she has been waking up for a few hours in the middle of the night. I can tell she's trying to get herself back to sleep- my fault for holding her back. Is it time to move to the crib!? Any mommies have experience with this? Please no rude comments itsmy first baby and I'm doing the best I know how. I just don't know what to do
