I'm not sure how old your dd is. Back when my dd was quite young and I was forever worrying about her getting enough and supply I would sometimes pop her back on the first side (I fed both sides and never pumped) and she would take some more. If your dd is continuing to pull off and not take more yet is happy/content I'd say she's full and doesn't want more. I would suggest a cluster feed in the evening and a dream feed, but again, not sure the age of your dd.
