2 month old won't nap

🐘🐘🐘 • 👧🏼 born 1/19/16. 👼🏼 lost 9/15/17. 👼🏼 lost 11/26/17.
My baby girl won't nap unless I'm holding her! I've tried to wean her but she'd rather stay awake and cranky instead of sleeping on her bassinet  or my bed. I wait until she's really knocked out and then I try to put her down. She literally wakes up as I turn my back to leave the room. HELP
