2.5 year old wont sleep!

My 2.5 year old will not sleep! Here’s a little background. So I took her binky away finally (I know I’m late please don’t give me a hard time! 😁) She honestly hasn’t asked for it and I thought I was in the clear. Then I noticed she wasn’t able to put herself to sleep without it. We slept trained her early so she’s always been great about putting herself to sleep. Now she’ll scream and cry because she can’t sleep. I have to rock her to sleep for both nap and night time and if she wakes up in the middle of the night she’ll be up for hours. Anyone else have this happen? Anything we can do to replace the soothing of the binky? Am I stuck rocking her to bed? I have a new baby and bedtime for my toddler takes forever. I didn’t think I’d be getting terrible sleep from my toddler instead of the baby lol.
