Sleeping tips

Please no mom shaming! My daughter used to be a great sleeper but since December has regressed. I am the only one who gets up with her since her dad works construction and needs the rest. The past few weeks she has been sleeping in her swing because I am so tired & also because she keeps rolling over in her crib onto her belly & forgetting she knows how to roll back 🙄 I don’t want her to continue to sleep in the swing because she’s about to outgrow it. I’d like some tips on how to get my baby to sleep better / longer in her crib. She used to do so good but not anymore. I’m open to all suggestions, except the cry it out method. Thanks!
