2 month old fights naps 🥴

I try everything. Rocking, walking, black light curtains, fan.. she nurses to fall asleep. Won’t take a pacifier. She’ll pull her hair, kick her legs, wack her arms and scratch when she’s over tired. I try to keep a routine, bring her up when I notice tired signs (45min-90). She’ll go from active sleep to wide awake. I’ve tried swings, different blankets, different clothes. This can go on for hours. Lately I put her in the car for a ride but once the car stops that’s it. I tried changing my diet to no caffeine and that doesn’t even make a difference. She sleeps decent at night but I’m exhausted. I don’t understand
