Still Not Sleeing Through The Night

My son has only slept through the night twice since being born, so I haven’t had a full nights sleep in a year.

I get ZERO help at night when he wakes up so when he does I just nurse him to sleep because that’s the fastest way to get him back down.

He will scream for hours when we have tried to sleep train him, he is extremely stubborn. He will not take a pacifier.

Any tips?
