Baby going more than 3 hrs to eat

Au

So my little girl is 3 weeks old, the past two nights she's been eating at around 9, not falling asleep until near 11 but then she won't wake in time to eat at her 3-4hr mark of 12-1am. Which I don't really blame her if she's not falling asleep until an hour before that feeding mark. I've been wiping her with a cold rag to wake her so she will eat but I was just wondering if it was something anyone else experienced?
