Sleep regression

Hi everyone! My baby slept through the night until the night she turned 4 months old. She is now 8 months old and is sometimes waking every hour!!! Sometimes wakes every 2 hours. We tried putting her in bed with us but she still wakes. At first my instinct was that she was waking because she couldn’t roll independently yet, but now she can and she still wakes up! I have thought about sleep training, but cannot get myself to do it. She is a wonderful baby, but gives me such a hard time when it comes to napping and sleeping for the night. It seems she’s never comfortable and I’ve tried putting her down to fall asleep on her own but she wants to be held, rocked, sang to, nursing or bottle etc. Any advice would be greatly appreciated.. thank you for taking your time to read this and hopefully to reply
