How to stop it?

My LO basically used my breast as a dummy,. How can I break that habit for bedtimes and through the night? She will only go to sleep while on the breast as a comforter.. so it’s pretty impossible for my partner to put her to bed as she just wants the breast.. she’s 9weeks coming up 10.
