I have high lipase. the twins have been drinking it fine but i recently tasted some and wanted to vomit. It was super soapy tasting. seemed to smell okay though. So how do you tell if nasty lipase milk is actually bad? will it change to the sour milk smell/taste that cow milk gets? They prefer it in a bottle i think but seem to drink it fine at daycare in the sippy cup. they will drink a little of it for us at home in the sippy but not surprisingly prefer it straight from me. they are now 13.5 months so i'm not too concerned that they get only breast milk.
