Help with sleep

My 5 week old hates the swaddle but sleeps good in it about 60% of the time when she’s really really tired, but usually fights and screams and cries when she’s swaddled. I don’t do it too tight. I’ve tried several different swaddle types, sleep sacks, etc and I just can’t find something that works for her. I’ve tried not swaddling her and she startled herself awake within 10 minutes.

She doesn’t sleep well. She usually sleeps from 10-1 and then is up every 1.5 hours to nurse until we get up at 7. I’m going back to work next week and I’m exhausted, I wanted her to be sleeping better at this point but she is exhausted too!! HELP!
