When will the witching hour stop?

Hey all, when did your LO grow out of their witching hour? Mine is 11 weeks. We cant get out of this routine- LO wants to sleep by 7 so we let her but she will wake within the hour and struggle with the inconsoloable witching hour cry til about 830 when she is calm enough to drink. From there she has a nice 4 or 5 hour stretch.
