When my 10 week old is not sleeping, she is screaming. I don't know how much longer I can take it.

ETA: My DD2 had it as well and she calmed down around 7 months (but is still rather high strung at 2 years). Hers seemed belly pain related, though, and DD3 just seems like she screams because she's angry.

She cries an average 7-8 hours a day.
