Sleep regression help!

Help! Baby is 5 months old and for the past 8 weeks we have been going through the regression. She is up every 30-90 minutes at night and only can be fed (EBF) or rocked back to sleep. Otherwise she screams. We are exhausted! She takes good naps during the day as I’m pretty good with her wake windows. Bed time routine is also good.

How can we get her to sleep longer at night as this has gone on long enough 😅 not wanting to sleep train. She does have reflux and eczema which no doubt contribute to the wakeups, just wondering if anyone has any advice. TIA ♥️
