I've been pumping for a little over a month and have discovered that my pumped milk doesn't keep well, developing a sour taste within 24 hours; it tastes somewhat like soy milk and not as sweet as when freshly expressed. Milk that I'd frozen for a few days and thawed under warm running water tasted the same, rather sour and not at all sweet. From what I've read, this sounds like a lipase problem.
I've been trying to build a supply and store as much as I can in anticipation of our twin girls who will be 6-9 months when they join our family. We're still a few months away from completing our adoption and I had planned to keep pumping, but if I can't use the milk, it seems somewhat pointless to be pumping 6 times a day.
I've read about scalding to stop the lipase action, but am concerned that I don't really produce enough at a time to make this work. I am currently producing a little over 5oz/day, about 2oz at the first morning pumping, 0.5-1oz during each of the remaining pumping sessions. I don't imagine that scalding less than an ounce will work very well, but if I wait until the end of the day the milk will already have an "off" taste.
In order to pump a greater amount each time, I'm considering pumping less often, 2 or 3 times daily, so that I can scald larger amounts of milk; I've read that a bottle warmer works well for this. Will my supply drop if I do that or will I be able to maintain the 5oz per day? I would resume more frequent pumping once we were within a month of travelling, to try to increase the supply, although I've been rather steady at 5oz for the past week or so.
I'm looking for any suggestions as to what to do about lipase (dietary suggestions, scalding or freezing tips, ...) and advice on how often to pump when we still have 3-4 months to wait. I was on the bcp/dom protocol for a year and currently take 120mg/day of dom and 3X3 tablets of fenugreek. It is my understanding that blessed thistle is more to aid with tolerating the fenugreek than to build supply, but if I'm wrong about this please advise and I will add it as well.
I really hadn't anticipated this and am feeling rather discouraged. Any advice would be very welcome.
