My daughter is 5 weeks old and unless she's sleeping or eating she's mostly crying 😯 Nothing is working and I cannot get her to stop crying. I had to lay her down a few minutes ago and she stopped for about 20 seconds and then started again. How long can you let a 5 week old cry?

I've tried all of these, am I missing something?!? She ate, burped, clean diaper, gas drops, gripe water, swaddled, no fever, no constipation, swing, bouncer, rocker, held her, walked around, talked to her, sang to her...
