Sleep help!

Alyssa
My 3 month old will not fall asleep by herself! For bed she only wants to be nursed to sleep and when i try putting her down after she falls asleep she wakes up crying. The only time she doesnt nurse to sleep is when I put her in her swing for her naps and i dont want her getting too used to that. She hates being swaddled and has never taken to a pacifier so thats not an option and i dont want to do the CIO option. Any tips will be super helpful!!
