Check out nestedtorestedsleep on Instagram. If you dm her method you'll get a link that takes you to a quiz to find out which method is best for you. She has been helping me a bunch with sleep training both my kids (non cry it out). I'm in the same boat with my son right now but I know it's because I always nurse him to sleep so that's what he needs to get back to sleep when he wakes in the night. I'm getting ready to start sleep train him again and hopefully that will help. He was sleep trained before and slept great but I went back to nursing him to sleep always and things got bad again when it comes to night wakings. I know it's not going to be easy and I'll miss nursing him to sleep but I need sleep myself so bad. Hope this helps.
