I'm going through the same thing with my little one. He's only 6 months tho. I was reading another post on here about sleep training cu I was thinking about the same thing and the advice on that one said you only stay in the room for a few minutes regardless of if they settle or not.. if I can find the post I'll share. There was a lot of advice on there from moms that have done it successfully

We are doing Ferber. It’s helping, but it’s hard. I stay about a minute. Usually it calms him, but for some babies it works them up more (like dangling a cookie and then taking it away lol) so I’ve seen a lot of parents start with Ferber and end up doing CIO because of that. Ferber doesn’t seem to have an “end time” that you give up, but I typically won’t let him cry over an hour total, and the chart goes up to 30 minutes without check ins but I don’t go over 10. We’ve just found that’s what works for him and us but all babies are different. It’s worth a try
TakingCaraBabies ABCs of Sleep is modified Ferber and will walk you through everything.
