I used a double pump with my 1st child and plan to use one again this time around. I liked being able to "pump quickly" if I was in a pinch for time by doing both at once.
I have a double pump but only ever did one at a time. Yes, it's faster to do 2 but I had to pay attention to make sure my suction was right and it was too hard to do 2 at a time.
Re: 1 boob or 2?
2. It cuts your pumping time down and they actually work better. (Just my opinion though.)
