Co-sleeping and self settle

AM

Hi

I co sleep with my baby for 3 months now. Everytime i rock or feed her to sleep and then we would lay down together at the same time

I wonder if it’ll be hard to teach her to self settle for sleep in the coming months? (Without being rocked/fed to sleep) (Because to learn self settle, she needs to be put in bed alone without me laying down next to her at the same time)
