Baby girl won’t sleep

Well she sleeps but here lately I feel like she goes to sleep easier for my husband. I feed her, burp her, and let her start to fall back asleep then I lay her down. This has worked fine. But the last week she just won’t go to sleep for me. My husband can do the exact same process and she’s out. It’s really hard on me. I can’t get her to nap during the day. I just don’t know what I’m doing wrong.

-She is 3 weeks old. How do I help her sleep better if she is over tired? I feel like I have tried everything
