My LO has been doing longer stretches at night which is great for me! However, I have been getting engorged only on one side, while the other side is just full. I nurse her from the engorged side and after 10 min, she's full, goes back to sleep and I just pump the other side. Is this normal? I get 4+ ounces from the other side after a few min of pumping. Do you think she's getting enough from feeding on one side after a 6-7 HR stretch? Weight gain and diaper output are good so far.
