So as you know I had been struggling with pumping enough milk at work to send to daycare so I've been having to mix Sophia's bottles with both BM and formula. Well a friend of mine let me borrow her Medela and I tried it when I got home tonight. I usually can pump only 2 oz. at night, but I was able to pump 4 oz! I'm hopeful that I can finally pump enough to send to daycare now and stop using formula! Yay! I have to say though, those Medela accessories are freaking expensive. Geez!
