Fighting sleep

Sarah • Mommy to Emmie Lou 💜. Nora Rose 💗. Army wife. Working Mama.
My daughter is 9 weeks old and has been fighting sleeping in the afternoon. She'll take little cat naps, usually nothing longer than 45 minutes. Then in the evenings she screams and screams because she is so tired. Yet still she fights going to sleep. Our usual methods (diaper, rocking, feeding, dark quiet rooms) don't work. Has anyone else experienced this?
