I have a cleft lip and palette baby so am exclusively expressing. I have an Ameda Purely yours and its great. You can control how fast and how hard it sucks. I get just as much with it as I did at the hospital. Just a note... If you can keep bub at the breast at all , do it!! Even once a day. Without stimulation from bubba, keeping up supply is hard!! I put bub on BB even though he cant suck just to keep the hormones aflowing!!! Congrats on still wanting your little one to get the best milk possible!! A little hint... double pumping is best, but annoying to hold both on at the same time... I cut vertical slits in an old maternity bra. I put the flanges through and clip up the bra. Hands free pumping!!!
