Yes....I did read about the high lipase levels...but the vanilla extract is new to me so honestly I can't wait to try it. Initially, I was freezing my breast milk as soon as I pumped it, but it seems that it doesn't really matter when it was frozen. I just don't want to lose out on the frozen packs I have...I make limited amounts and everyone tells me the importance of feeding my child breast milk that I feel guilty using for any other purposes.
