When does it get easier?

My baby girl is 2 weeks and 1 day and while it's not crazy difficult she does like to comfort nurse and she cluster feeds. So pretty much I feel like she always wants to be attached to my boob. It makes thinking about going and running errands sound very difficult since I can't whip my boob out in public every time she cries.... 
I'm going to start pumping this weekend to have a bottle on hand but not sure if that will really help with being able to calm her in public. 
So... At what age do you think things get easier? And how so?
