Breastfeeding A 1 Month Old

Is it ok to not feed a 1 month old for like 5 to 6 hours? I don't mean to do that or do it all the time but at night I just wake up when she cries and feed and change her but the last couple nights she sleeps for a little bit of a longer stretch before getting hungry again, is that bad for her or is that ok if it's because she's asleep?
