Newborn sleep advice

Kaye • OB/L&D TECH. Second girl due in November. Hoping for a vbac

My three week old will not sleep unless she’s being held. We’ve bought numerous things for her to sleep in and she won’t sleep in any. What Can I do to get her to sleep in the bassinet. I’m so so tired of being awake all night trying to get her to sleep I just need some advice. We swaddle and she loves her swaddle but not when you lay her down in something other than your arms.
