Cosleeping habit

So my daughter is 4 months old and my goal was never to cosleep. She has always slept in our room and has either slept in bed with me (please dont tell me about the dangers of this, because I make sure she is safe) or in her bassinet. I went back to work about 2 months ago and since then, I have developed a bad habit of just pulling her into bed with me when she wakes up to feed because I was so exhausted and now shes having a hard time sleeping without me.

We have a solid night time routine and she originally goes down in her bassinet, but she wakes up MULTIPLE times a night and I just cant get her to fall back asleep in her bassinet anymore.

What are some tips to break her of the cosleeping? Thanks in advance!!
