How long do you usually pump for each session? 

This is my second baby and I usually only pumped about 20 minutes with my first baby. This time I have to pump about 45 to get some good ounces. This is so time consuming! I nurse when I'm home but I am starting back to work Thursday so I'll be pumping in the morning, once at work and at night before bed. So I'll have to stay up late and get up early before baby to pump and 45 minutes is a long time! I'm already stressing! I ordered new parts even though I had already gotten new flaps. I'm hoping the new parts help! I really want to make it to a year like I did with my first son.
