Reflux baby=no sleep

Anyone having luck with their reflux babies sleeping by themselves??? My 2-month old only sleeps in our arms in a recliner, we are trying to break that habit now, we’ve bought every type of insert for her crib with no luck, tried elevating a bit with no luck. Does not like to be swaddle with her hands tucked in, we’ve tried the Halo sack, the nested (the weighted blanket like sac), no luck. She’s eating fine, gaining weight fine, so no medical intervention is necessary, but we need sleep!!

She is bottle fed breastmilk, we use Dr. Brown’s bottles, she is fed upright, we burp her often, she does spit up a lot, she is kept upright for 30 min after feeding, I have changed my diet (with no significant change in her reflux), this past month has felt like a whole year!! I need sleep!!! HELP!
