I NEED to sleep train my baby but I don’t know if I’m ready 😔

So I’ve been cosleeping with my son for the past month. He went from waking 3-4 times a night to waking every hour. I had to do it for my sanity. He still wakes up about 3 times a night, even if we cosleep. He’s EBF and wants to eat every time he wakes up at night. I need to start sleep training or I’m literally gonna go crazy from sleep deprivation. But I’m scared that I’m not emotionally prepared to let him CIO. Any advice or tips? I’m gonna miss sleeping with my baby but this momma needs sleep...
