I worked at an ob office with dd#1. They were so great about my pumping schedule. I returned to work at 6 weeks as i did not have vacation built up and could not afford to continue unpaid.
I pumped until 11 mo, because my supply had substantially dropped and it caused me more frustration than I needed 3x a day. I continued to nurse at home and used up my freezer stash than switched to wcm during the day. I also was using fenugreek and more milk plus, which had worked earlier, but no longer.
This time, as a sahm, I will pump for a stash, but plan to nurse nearly exclusively, so I hope my supply will last until we are both ready.
