long sleeper??

tmp-9062138

So the last few nights my LO who is a week, 3 days has been cluster feeding, which I assume is pretty normal around this time. But today shes been asleep and not wanting to feed for almost 6 hours. I've woken her up and tried to get her to latch but she just ignores my boob.and falls back asleep. Is this normal? What should I do?
