Sleep deprived

Hi I’m a FTM who exclusively breastfeeds. My almost 3 week old is refusing to sleep unless she is attached to my nipple or in my arms I’m not getting any sleep, she wakes up so often because I put her in her bassinet or her dad holds her and she doesn’t like that. I need advice with how to get her to stay asleep in her bassinet so I can get sleep she literally spends hours at the breast not even eating just sucking gently on my nipple like a pacifier mind you I do have a pacifier for her but she refuses to take it
