I'm no expert but it's important to get 8-12 good feeds in any 24 hour period so if baby sleeps for a long time after cluster feeding for hours, for example, then it could be fine (after the first few days of life).
Also, has she just had a growth spurt as they tend to sleep more afterwards? I doubt it will continue too but, if it does, just keep an eye on the overall feed pattern, weight gain and the number of poopy diapers. If weight gain falters then you may want to consider waking her for a feed.
Congratulations Jade!
