Baby only sleeps when held...help!

Our daughter is 12 days old. A couple nights ago she did an amazing job sleeping in the bassinet. But now, the past 2 nights she will only sleep if one of us is holding her.

I’ll feed her and then try to put her down, but within 2-3 minutes she’s crying to be picked up. I’ve tried setting her in the bassinet when she’s awake, drifting off, and already asleep. We e tried dressing her in a sleeper and in sleep sacks. Her one sleep sack wraps around her like a swaddle.

I don’t know what to do...My boyfriend and I have to take turns being up with her all day and night because she won’t let us put her down. Makes it almost impossible to do other things like pump or shower or nap, etc, etc...

Any advice??
