Does anyone know if the amount of lipase can vary and not always have an effect on the milk? I have noticed a couple of bottles turn soapy smelling/tasting and I am trying to determine if that means all of my stored milk will turn this way. I have an entire deep freezer full of milk and I am hoping that it's not all bad. My LO takes pumped milk 3 days per week when I am working and he is nursed the rest of the time. I have stored his bottles of milk in the refrigerator and it seems that they are okay for a few days. I tested some milk that was 5 days old and it had the soapy smell. I would prefer not to have to scald my milk if I don't have to because I know that it looses some of its anti-infective properties. I am wondering if I might need to only give LO pumped milk that is no older than a few days and then scald the milk that I have to freeze? My LO is not thrilled with taking the bottle, but tolerates it okay. I am wondering if part of it may be due to the change if flavor with excess lipase.
Thanks in advance!
