One of the most frustrating parts of pumping for my wife has been transferring milk into the Motif storage bags. It can be difficult to hold the bag open and upright while pouring into it. I designed the Baggie Buddy to help with this. The push pin locks in place to hold the bag open and the stand allows the bag to fully expand as its filled. I recommend filing the top and bottom surfaces of the push-pin slot with a fine file and breaking the edges of the push pin. This is not necessary, but makes operation slightly easier. 

Directions for use (version 1.2). Gently squeeze long legs of push pin and insert into slot from the inside, pushing outwards. This will allow the pin to be retained within the frame. To use, tear off the top of the Motif bag and open the ziploc. Insert bag with pour spout on the thicker side of the Baggie Buddy. Gently squeeze the two long legs of the push pin together and push toward the bag until the two pins at the back are in place. To remove, simply squeeze the push pin legs together and pull back fully until the forward pin stops are hit, zip bag, and remove!
