Lovely

My baby girl is 5 weeks old. She only sleeps when I or her dad held her, as soon as we put her down in her bassinet she’ll wake up or she only sleeps an hour long and that’s day and night. When she starts crying, I have to pace around the bedroom in the middle of the night 😡I’m not getting any sleep, I’m so exhausted and angry. I want to enjoy my baby but I just keep having a bad negative thoughts. She’ll not take a paci so she’s always on my breast. She sleeps longer if I’m holding her. She is breastfeeding. Please let me know how I can get her sleep longer and on her bassinet. I tried to co sleep but it didn’t work.
