When does it get easier

My 7 week old still screams so bad every evening no matter what we try. She won’t eat my husband hold her or feed her she only wants me so I’m having to hold her for hours and hours while she screams and do all the feedings every night. And she only sleep for 2 hour in between each feeding at night.

When does it get easier idk how much more I can take 😫😫😫
