Sleep training

If you did a sleep training what did you use? I finally have a week off work and I’m ready to try something. This kiddo is super sensitive so if any mommas out there also have a sensitive baby and found something that worked let me know! I’ve tried having him cry but it ends up ruining the whole night and then he WILL NOT let you lay him down at all...! Lately he is up a handful of times at night, I’m exhausted, he’s exhausted. I am finally ready to try something. I hate to admit but he has been co sleeping since about 3 months just for us to get sleep but it’s not good for either one of us, no one is sleeping now 😩. So any advice would be so helpful!! I want to do it with him in his own bed. No more bed sharing for us!
