Hi! Im a stay at home mom to my first baby, and im 6 weeks pp. ive tried the Momcozy pump but im so large chested that the motors keep popping off the collectors and i sometimes leak milk everywhere when the silicone flanges accidentally pry open when i move around. I just need to be able to pick up my baby and change a diaper while pumping; and sometimes i pump a large quantity (early morning), but usually 4oz per breast. Ive read many reviews of these 3 popular pumps and im ready to invest in onr. Just wanted some reviews to gauge which seems to be the best fit for me. TIA!
