Baby sleep

I haven’t had the easiest time with this baby and sleep. Even as a newborn he wouldn’t fall asleep unless you held him. He wouldn’t stay in a crib or bassinet so I caved and he slept with me. Well I was able to get him finally to sleep in a bassinet and was in a good routine of 4-5 hours then another wake in the night. Then I think the 4 month hit and he started waking up every 2 hours. That resolved and he’s sort of back to the sleep pattern but now when he wakes in the middle of the night he doesn’t just fall right back asleep from feeding. He fusses so then I have to walk him around the room but now even that is becoming difficult cause he moves around in my arms like he doesn’t want to be there. He’s just super restless and won’t drop off. If I put him down he curls his body rolling back and forth and cries until he’s wide awake. I know the only thing that will help with the night waking will be sleep training. I tried it like a week ago and I couldn’t let him cry longer than like 30 seconds. He won’t keep a paci in his mouth for longer than a min. I’m just at a loss. He doesn’t even like me sitting down and rocking him. Anyone can relate or have suggestions?
