Working mommies how long did you breastfeed?

Di

My babe is 6 months old and has been exclusively breastfed. Started solids this month. I love nursing him when I’m home but I can’t say I love to pump. I’ve been back at work since 9 weeks pp and I pump 3 times a day at work. I’m gone about 11 to 12 hours per day. I have a stressful demanding job so finding the time to pump each day adds to my stress. I work at a few different locations so I’m always carrying around a huge bag of stuff since I can’t leave anything at work. I want to keep breastfeeding but not sure how long I can keep pumping for without going crazy. I push through every day for my son. How long did you mommies breastfeed for? I’m wondering if at some point I can drop to two pumps per work day and then eventually one?
