Pumping question

Jennifer • Fri, Oct 11

I keep reading posts where some ladies say they pump x amount of times a day for like 30-40 min per session. I thought pumping for more than like 20 min was bad and could cause damage?? Plus I can only pump for 10-15 min tops then my milk slows or stops. However I am breastfeeding also in between pumping so maybe that's why my times are shorter? Just curious if I should be pumping longer periods?
