4 Month Sleep Regression Tips?

I think my LO (14 weeks old) is starting the dreaded 4 month sleep regression. She has always fought her naps but has never really had problems falling asleep at night once we put her down. However it has now been almost 4 hours of trying to get her to sleep and she has only managed about half an hour at a time before she wakes up crying until i’m able to rock her back to sleep...rinse and repeat. I know this is developmentally normal, but any suggestions or tips to help us get through it would be appreciated! Thanks!
