If you think of lipase-rich milk being like buttermilk (which it's not really but it's a good analogy), some people like buttermilk, some don't.  Once the lipase has activated, you can't really undo the effect.  You have to flash-heat right after pumping before storing.  My advice? Give it to baby.  It won't hurt.  Don't taste it yourself.  Or smell it.  Or make a face.  Anecdotally, my ddil made kiefer milk and wanted the gbaby to try.  When he saw me down it and go "yum", he took some and loved it ever since.  No sweetners needed!  How many babies have you seen enjoy lemons or other sour tastes?

I don't think there is anything she can do to make the taste go away, but her baby may still drink it.  If the baby wont drink it she can use it to make other foods when the baby starts solids.  I made cheese sauce once with frozen breastmilk and it tasted fine, my milk didn't taste great out of the freezer either.

We know that in the future she must bring her freshly expressed milk to a simmer prior to storage, but what about all of the milk she wants to thaw?
