Taking cara babies

Okay guys, please don’t judge me. My little guy is 6 months old, and I have yet to get more than 4 hours of sleep. Especially this past week, he is up every two hours, and I can’t cope anymore. I have no help and am trying to survive this sleep deprivation on my own. I have heard amazing things about taking cara babies, but unfortunately I just can’t afford it. We are a single income family, and I can’t drop $200-400 dollars on the program. I’m just wondering if anyone on here can go over the basics for me on the program 😂. I’ve tried everything, except CIO methods because I just can’t handle that. He was bed sharing up until 5 months old, and I still can’t get him to sleep without nursing. He always puts up a huge fight lol. Please SOS.
