Help!!

Any suggestions on getting my 3 week old to sleep in her bassinet at night? I have held her, while sitting in a recliner, all night since we’ve been home from the hospital. My husband wakes up about 5am and takes over and I go to bed. He goes back to work in Dec and this just isn’t sustainable. We have been working on getting her in the bassinet the last 3 nights. She does great in it during the day, but when night roles around, she’s not having it.

What we are currently trying: We are swaddling her with a Velcro swaddle, playing white noise, and rocking her until she is in a deep sleep. When I lay her in the bassinet I lay her feet first then butt the head because I read this keeps from bringing on the startle reflex that wakes them up. Sorry for the long post but We need help. Nothing is working. I dont want her to “cry it out” because I’ve read babies this young can’t sooth themselves. But I am open to anything at this point.
