Kudos to your pumping, prayers and hugs your way, LD. How many ounces are you getting per day? You may start running out of space. One tip is to store the bags flat ... it is helpful to do this in a sandwich size tupperware container until the bag is hard.
You might consider buying a separate deep freeze (temp is below 0 degrees farenheit. I've seen small chest freezer's at CostCo for $179 or you might get lucky and find one in the classifieds from a moving sale.
Keep up the good work, LD!
