My kid won’t fall asleep on her own!

Like the title says, my baby girl won’t fall asleep on her own. Lately we’ve been able to shush while sitting in a chair for 10 minutes then we walk out. But for the last week or so she won’t fall asleep and it’s been taking 30-60 minutes. She also wakes up 1-2 times a night still. I’m at a loss for what to do. We are tired and would love to get a full nights sleep!!!! Any and all advice appreciated.

We attempted CIO. I just couldn’t handle it. After 40 minutes she was still crying and it was just getting worse. I don’t know what to do. I tried ferber but she would cry even harder and worse each time I would go in and then leave again.
