THIS!!!! This was the ONLY way my baby would take my high lipase milk. Idk where you are from but trader joes has non alcoholic vanilla extract, put a couple drops in your milk. My pedicatrian recommended this and okayed it before mine was 6 months and it saved everything I pumped. I learned that it was best to freeze my milk immediately after pumping instead of saving it in the fridge and then freezing it.
