Expressed milk tasting "sour" (xposted in "challenges")

[Lyndzies]

So, I think I am one of those mamas with excess lipase enzyme. I don't know why were only just discovering this (DD is 6 months on Friday), other than the fact that Cady was refusing one bottle in particular from my MIL last week, and I tasted it when I got home and UGGGHHH it was definitely sour (had only been in the fridge a day or so, and handled correctly).

I pumped her bottles for today on Thursday of last week, tasted them this morning, and they are starting to taste sour too. Hopefully she will eat them (I sent a couple bags of frozen just in case).

I dunno if I just started producing excess lipase or what, but we have only had this problem once or twice in the past, which I noticed only because I was feeding her some rice cereal mixed with BM and tasted it first to check the temperature, and it tasted nasty... As a full-time working away from the home and pumping mama, I just can't realistically see adding scalding the milk to inactivate the lipase as a viable option for me. The thought of adding that to my evening's to-dos makes me want to cry.

We will have made it to 6 months on Friday, and I guess then we'll see what's what. Only 3 bags left in the freezer, and I'm officially more discouraged than I've ever been. Thanks for letting me vent, mamas. I am not ready for our BF'ing relationship to be over, and even though it's not (yet) I already feel like I'm starting to mourn it. :-( Any advice/encouragement appreciated.

I think I responded to this in another thread but the scalding thing isn't that big of a deal.  The munchkin warmer is easy to trick into getting the milk hot enough.  If you are interested in specifics feel free to message me.

I think it would help if you figured out when they started to taste bad -- does the milk taste okay after it's been expressed less than 24 hours? When does the lipase start to take over?

Could you get into a groove where you're sending milk pumped the day before (so the milk you pump at work on Monday is fed to your LO on Tues, etc.)? That way, you'd probably only need to scald milk on Friday.
