21 mo still nurses to sleep- advice on weaning and starting independent sleep!

My almost two year old is glued to my side 24 hours a day, 7 days a week. I’m a SAHM & we have no family or friends as we moved out of state. It’s just him & me all day, 5 days a week and when his dad is home on the weekends it’s largely still us two.

He has a hell of a time sleeping and as of right now, I’ve been nursing for an hour trying to get him down. We have always co-slept and it’s been fine but my husband and i are ready to start getting some alone time back & i would like to help my little dude become more independent.

I know if i were to start popping him in his crib and walking away, he would LOSE IT & i wouldn’t be able to follow through. I just am looking for some tips on how to wean/stop nursing to sleep & start getting him more comfortable falling asleep on his own. Thank you!
