    Default Sour Milk

    Hi Ladies- My LO is 7 months old, and I've been pumping 3x per day at work for the past 3 months. I put my expressed milk in the Lansinoh milk storage bags, and place them in a cooler with two ice packs. I heard that you aren't supposed to combine refrigerated milk with freshly expressed milk, so I combine the expressed milk after they've been cooled to the same temp for a few hours. As soon as I get home I put the milk in the freezer. I'm finding that a lot of the milk I thaw out is sour. So... I don't know what to do differently. Any advice? I feel like I'm having to toss a lot of milk these days... and since I already have to supplement, this really sucks!

    Check out the lipase thread! Don't toss it! Save it for making food IF baby won't drink it.

    your milk is not sour.... your milk contains the enzymes required to begin the process of digesting its self for the baby. it is only when this milk is stored for later use it becomes less palatable. there is a link under the Resources tab on this website,(see above) with info on how to fix this issue.

    Have you tried letting your baby taste it? If collected/stored properly but still smelling "off" to you, yet your baby drinks it, it's fine.
