Is 2 week old getting enough?

Alex

So my baby is 2 weeks old and I’m exclusively breast feeding. I think she is getting enough milk because she is happy and sleeps good and has a lot of dirty diapers. But sometimes during the day I can’t get her to feed for any longer than 6-8 minutes and only on a single side and she won’t be interested in eating again for 2 hours. Other times she will feed for 10+ minutes on both sides. She behaves the same way after short and long feeding.
