sleep training help

My 13 month old boy has never slept through the night. I nurse him to sleep, but now he can’t go to sleep without nursing. And he wakes up multiple times a night & has to nurse to go back to sleep. He ends up sleeping in our bed most of the night.

We tried to put him down in his crib after bedtime routine last night (pjs, books, nursed him), and he just stood up and screamed. I went in after 5 mins and comforted him, didnt pick him up, and he just cried more and more.

My heart can’t take the crying it out method, but I am at a loss of what to do. I am exhausted, and I want to move him to his crib. Any advice? Resources?? Thanks!
