Anyone else's LO hit the 4 month sleep regression? PLEASE HELP

Lynn

I dont know how to help my little one anymore feels like I've tried everything. I can no longer swaddle her because shes starting to roll so I use a sleep sack but shes waking up every 40 minutes at night. I haven't slept at night in over a week and I'm exhausted. I feel like giving up and cosleeping with her, before this regression and swaddle transition she was sleeping 7 hours straight before waking up to eat. any tips or advice is appreciated

I do use sound noise and room is completely dark she just doesn't seem to settle only for about 30 min and then I watch her kick and wiggle around for another 15-20 min before she starts to cry.
