Newborns can be very sleepy eaters, so it can often be hard to get a full feed in the first few weeks before baby falls into a coma like sleep (tips on keeping sleepy newborns awake here). If baby isn't able to get a full feed, then she'll likely feel hungry much sooner than if she had a full feed. Just do your best and feed baby when she is hungry. She will get less sleepy soon and full feeds will be easier to get. Read more about full feeds on this post.
A well rested baby will eat much better than a tired one. You'll struggle to get full feeds when baby is overtired because she'll be too sleepy or fussy. This means that while you may be trying to work on having baby learn to fall asleep on her own, you will also want to make sure this doesn't results in her being too overtired. This is a tricky balancing act, I know!
