How to transition baby to crib?

Our little one is 2 months old almost and we're having trouble putting her down. She used to be okay in her bassinet, but she will only sleep in it at night. For her naps she will only sleep on us or in her bouncer and the second we lay her down she wakes up. I tried putting her in her crib once a day for a nap and the longest she's lasted was half hour. I think she has very mild reflux so we tried keeping her upright for a while and letting her sleep at an angle, but I worry that this constant habit of only falling asleep on us is going to cause problems when it comes time to go in her crib. She's already getting close to too big for her bassinet.
