I freeze a lot of things for our little boy. When he was first born, I froze a lot of breast milk. *Don't stop reading*
Then I threw it away because it had ice crystals which formed on it and I deemed this to be dreaded 'Freezer Burn'. Breast milk is also known as 'Liquid Gold' so it was REALLY a sad day when I put it down the garbage disposal.
I am now kicking myself for doing so after reading this post...it wasn't really freezer burned. This applies to a whole lot more than just frozen breast milk, by the way. It's worth it to click over so you don't waste your food.
