I decided I should rotate my freezer stash and last week I tried giving DD 1 sippy or bottle of my frozen Bm a day. She's been refusing it! It's warm, not sour, etc.; been in the deep freeze for 34 months. It does smell a little plasticy but I read that's normal. I tried mxing half fresh with half frozen and she'll drink a little bit of it, but not a lot. I started ready about a possible lipase issue but I'm hoping you ladies can break it down into laymans terms or give me some good websites to read about! Also, if it is a lipase issue, can I still donate it to the hospital or is it just bad milk?
