Sleeping in crib.. Help!!

Since my daughter came home she was all about her rock n’ play. She wouldn’t sleep in anything BUT it. We gave in & figured as long as she’s getting sleep & her reflux is under control, why not. Well fast forward to being 5 months & this girl will not transition to her crib. She absolutely hates it. She wakes up every 30 minutes screaming & nothing can console her. If I get her to fall asleep in my arms she wakes up the second I try to put her down. My question is, how do I transition her to sleep in her crib? I saw wedges for sale but I don’t want her to become reliant on that & then have to take that away too..
