Freezing and Storage of Breast Milk:
• Make sure you wash your hands thoroughly with soap and water before handling pumping equipment, pumping, and breast milk.
• For bottles: Just put in the back of the freezer or towards the bottom in a box or basket to organize. You can stack cardboard between each layer of bottles to allow for safe and easy storage where they stack neatly.
Be careful with glass bottles. Not all glass is tempered for freezing and there is a huge safety risk of the bottles cracking or breaking and tiny glass shards getting into the breast milk, even with out you knowing. This is especially risky as liquids expand when frozen. Check glass temperament ratings before using, if unsure... don't risk it. Glass is also not very safe to ship.
*For breast milk bags: Place a cookie sheet or even sterile piece of cardboard with sterile wax paper on it that fits your freezer shelf. Lay your breast milk bags flat across the surface. Bags will freeze pretty fast, usually with-in a couple hours to a day depending on how much cold air circulates around them.
• After your breast milk bags are frozen and you have enough to fill a gallon size freezer ziplock bag it's time to transfer them. Take the ziplock bag and label with corresponding dates from the breast milk bags such as 1/1/2017 - 1/3/2017.
• Put the frozen breast milk bags into the ziplock bags by laying in a back and forth method to get the bags to fit better.
• Zip the bag up most of the way, then press out the air, and finally zip completely.
• Place the packaged ziplock bag in your chest freezer stacked neatly and in dated order.
