I had a manual single pump i used to use and could only get 4oz out if i pumped. My sister bought me a medela in style electric pump and im getting so much more out! We found it on sale for 190$ at walmart. :D so crazy! Now i have 700+ ml. Stored in the freezer for safe keeping! So pumped. Befkre i could never store any because he would get so hungry and my supply was running low. Since ive been pumping and using my oils my supply has grown and i am SO happy!!!!
