I'm exclusively pumping 10x/day now, and pumped 50% of intake with DS#1 for 13 months. Both had latch issues, I'm about to go to a 2nd lactation consultant for another opinion. My two cents are (a) fenugreek can have side effects, it gave DS#1 and me tummy trouble (I wished someone had given us a heads up before we spent days figuring out what was wrong!), and (b) I found the hospital pump way better for keeping up my supply than the purchase pump. I seem to have really sensitive supply in general (dropped 30% when I had mastitis this time, and was up and down last time every time I took advil, missed a pumping, etc.), and I think others are fine with the store bought kind, but I found the symphony much more effective & gentler.
Good luck, I hope switching works out for you (I am hoping I might be able to do the same!).
