Ftm feeding question

Jade • Mommy to Rylee 2-3-16. To be married 5-29-16
So the hospital wants me to feed my daughter every two to three hours, but I've been demand feeding her. So she'll eat cluster feeds an hour and a half apart twice, then won't wake up to eat for four to 5 hours... Is that okay or should I be waking her up to feed? She only does this once a day where she'll not wake up for a while
