Re: bottle refusal... not in the way youd think.
It depends on how long it takes for the lipase to become active in your milk. This varies from person to person. To find out how long your milk is good (the longest you can wait before scalding), put a bottle of freshly expressed milk in the refrigerator and smell/taste it every two hours until it starts to smell/taste off. If your milk turns in less time than you would have from your first pump and the time you get home, then you can use a bottle warmer to scald your milk at work. Scalding always works to inactivate the lipase, but it needs to be done before your milk starts to turn.

Has anyone ever heard of anything about something in our diet contributing to excess lipase activity? It seems like it has only become a problem within the past few weeks, as he has been bottle fed frozen milk since he was 6 weeks old and has never refused. And my milk only goes as far back as May in the freezer. Could it be something I am eating? There is a frustrating lack of information on this issue. I want to make sure he is getting what he needs during the day.
There is not much information on diet and lipase, and I don't think there is much that there is much that you can do diet-wise. However, there are a couple of things you can try mentioned in this thread.
Honestly, scalding is more likely to work than changing your diet. Scalding works for all women as long as it is done before the milk starts to turn. If there was a dietary change that worked for everyone, then you would probably hear about it pretty frequently. You can try some of the things listed in the links above, but be prepared for the possibility that you may have no choice but to scald your milk.
Is your baby drinking the unfrozen milk consistently? If so, you may be able to just leave milk that you pump the day before. I had 48 hour before lipase began to turn my milk, so I only needed to scald the milk I pumped on Fridays. Have you tried giving freshly expressed milk (not from work, pump and immediately offer the milk) in a bottle to make sure that the issue is not the bottle?
