Transitioning to Pack'n'Play

Adrienne🦋
Hi, I'm a new mom who's baby just turned 2 months old! She's been sleeping in the bassinet that attaches to the pack n play but she's getting too long for it, so it's time to transition her to sleep in the main part. She's swaddles every night and has to sleep inclined because of reflux. Does anyone have any tips on how to transition her? She has a crib in her room, but I'm trying to keep her in my room for awhile, that's why I'm using the pack n play. Thanks in advance! :)
