Still nursing to sleep. Help!

Samantha • TTC BABY #2 !

I'm still nursing my baby to sleep. She's 9 months old. I've tried having the same routines and putting her to bed but she will cry forever. I've tried going in and talking to her / comforting her every 15 mins for over an hour and she still flips as soon as I put her down. What are some things you ladies are doing to get them to go down in their bed ?!
