What's wrong with the left?

Miranda
I need some help here mommies I'm exclusively breastfeeding my son and he is great at nursing he's only about 2 weeks old, in the hospital he favored my left breast but still nursed off of both, the past 2 days I've noticed he will latch onto my right and stay and nurse but he won't latch onto the left and if he does its only for a minute, he will suck a little bit an open his mouth but won't latch. Does anyone have any tips or anything to help me out or know why he might be doing this?
