Looking for hope… is it possible to reset sleep habits for 2yo with a move?

Long story short: my 18mo’s crib is in our bedroom. There’s no space anywhere else. She is up at night a LOT these days, and it’s been really rough. Like, really rough. When she wakes, she shrieks “mama!” over and over until I come and nurse her in my bed. I’m exhausted and depleted.

(Side note: please don’t shame me for creating this habit. It’s been really hard. I feel terrible about all of it.)

I’m looking for some hope… has anyone successfully reset a toddler’s sleep habits at/around 2yo after moving houses? We plan on finding something bigger so hopefully she can have her own room.
