Six month old wakes 5-6 times a night

About six weeks ago we moved our baby from the rock and play to the pack and play to sleep. Since switching, her sleep habits have gotten gradually worse.

This past week or so she has been waking up five or six times per night. Out of habit and desperate need to sleep, I nurse her back to sleep every time.

I’ve tried everything to get her to sleep more... less day naps, more day naps, nightlight, no nightlight, fan, no fan, swaddle, no swaddle, different bedtimes, etc. She had a consistent bedtime routine and we practice safe sleeping methods.

I am honestly at a loss. I need to sleep more than an hour and a half at a time 😭 Has anyone experienced this and actually found a solution?
