Crib training

Hi moms

My son is 8 months and he’s been falling asleep in our bed , then I transfer him in his crib only at night. His nap his in bed I’m breastfeeding so I found it easier to feed him laying down . Then just leave him in the bed. So I’m hoping it’s not to late to transition to his crib , it’s effecting my sleep since I don’t sleep well at night he still wakes up every 2-3 hr at night , when he’s up he cries cause he realizes he sin his crib I nurse him he falls asleep in my bed then I transition in his crib . Some nights he seems to be up every hr😣😣 those nights I’ll have him sleep with us. Where do I start I’ve try the cry it out method not for long it kills me so hard for me. He’s cry up to 45 min of course I’ll go in reassure him I’m told him I loved him , but it only seems harder for him.:(. I need time for myself so I’ll love him to self soothe with out me . HELP!!! I’m open to suggestions, different techniques what worked for you ?!
