Freemies! Quite possibly the best invention ever. Attach these milk collection cups to your electric breast pump using tubing, and pop them into your bra. Pump with no hands! I used to pop these in and pair them with my fully portable Spectra S9 pump and walk around pumping with no one the wiser. I could not have exclusively pumped for 8 months without these, they are an absolute life saver!! Sometimes they do leak just a few drops, so I would tuck a paper towel in with them at the bottom to catch the drips. It wasn’t even a measurable about of milk, just an annoyance, and it happened from the day I got them, so it’s not from overuse. I found that the quicker and firmer I snapped the pieces together, the less likely they were to leak. These cups can be adapted to work with any electric breast pump, just ask me how! #moolafordebt
