Help!

Hi! My LO is 6 months and since 4 months hasn't really stopped coming out of the sleep transition. I've probably only had a week of good sleep since she was 4 months. At first I thought she must be hott so I changed the position of the fan to face her so she doesn't feel anything. I also changed her to the halo sleep transition sack (the quilted one). She still sleeps in her bassinet because I don't have space for a crib and my toddler sleeps with us in bed so I can't keep her there. I'm losing my patience over sleep now because she tosses and turns throughout the night and just cries to be adjusted or have her pacifier put back in her mouth. Idk what to do I'm having to just feed her again around 2/3a and then she's up again crying and wanting to be held at 5/6a. I start work in a couple of weeks and I can't deal with this constant waking up at night. It's not sustainable. Any help on what could be baby girls issue or what I can do to make her sleep through the night ? I never had this issue with my first born, she had slept through the night even if it was only 6/7 hours, but this one barely sleep a stretch of 3 hours 😩
