HELP! Baby will only sleep in my arms

So I’m having a lot of trouble with my baby sleeping if I’m not holding her. I was wondering if anyone else was having this problem, and what they are doing to help? I don’t want her to be unsafe sleeping with me in my bed, but if she does sleep with me she does 4-5 hour sleep stretches. She won’t sleep more than an hour at a time (max) if she is in her bassinet. I had thought about doing a baby hammock but I have read that can be unsafe as well, although it is probably more safe than her sleeping with me.

Does anyone have any recommended products or ideas I can try? I appreciate any help!
