I'll be a stay at home mom, it's my third baby, second attempt at breast feeding. My first child I didn't even attempt because I was nervous, scared, new all in one. My second child however I tried everything and it was excruciating. My nipples bled, my breasts got small amounts of clusters and she was lip and tongue tied. I also never made enough to save and feed through bottle. This round I'll eat healthier talk lactating medicine if need and do some real hard work to keep producing. But my question is what is the best pump and why? I had the madela and I liked it but I didn't understand expression and let down. Please help me.
