Pumping

T

How do I know if I’m pumping correctly? Name a few of the must do’s. My boobs are tireddddd. I feel like I just got nursing down and then there was pumping. It feels like everytime I sit to pump the baby smells my boobs because he wants to latch. I wasn’t successful doing the latch and pump at same time. So far it’s my third day and I’ve been able to do 2.5 oz only a day. I cannot continue at this rate. Help.
