Frozen Breastmilk and Taste???

It should be fine. Maybe it was too cold still, too warm. they like it room temp like when it first comes out. if she still won't take it, you could mix it with fresh that you just pumped and use it that way. yellowish should be normal, just stir it up. maybe let it sit out to get to room temp or maybe warm it a few seconds.

Did you taste it?
I don't remember the technical term, but some women do have an issue with stored breastmilk, where the milk gets a "soapy" taste to it. Lipase is the word that's stuck in my head, but I'm not sure.
You may want to check what you've stored more recently to see if that's the case.

Ooh! I had the right word!

Hasn't gone bad, you body makes different milk based on the age of your baby (different taste but also different nutrients, based on what your child needs at that age)

You could try making yogurt with it, it would really alter the taste and is a great 1st food for baby.

Carrie W. is completely right, as the same exact thing happened to me and was devestating. My milk, once frozen even for ONE OR TWO DAYS started producing an enzyme called lipase, which eats away the fat in the milk and causes it to taste a little soapy rather than fatty and sweet, as BM typically tastes. I'm pretty sure it's still safe to drink but it may not be as nutritious and certainly not as tasty. My son drank the milk like this for a few weeks but then started to turn away and reject the bottle. We couldn't figure out what happened, until we started defrosting all of my frozen milk, experimenting with it and found that ALL of my milk had this yucky taste. I researched it extensively, talked to two lactation consultants, and my pedi and there was nothing I could do. I learned that I could hold the milk in the fridge for up to a week and then toss it but there was no use in freezing it for me, as it would pretty much go bad. I say this was devestating because I pumped like mad, hoping my son would be able to exist on my BM for six months after I stopped nursing. I pumped so much that I filled up 1.5 of my own freezers (we bought one just for my milk), my sister in law's freezer, and two of my friend's freezers, and all that milk went to the garbage. It's completely awful but at least you now know and may have to pump less. I'm sorry - it sucks big time either way.

I was told 6,6,6...6 weeks in the freezer, 6 days in the fridge, and 6 hours on the counter.

My milk did it too. It was very frustrating to me. It was a big waste half the time to even freeze it. I just ended up putting it in the fridge and using it before it went bad. I don't really know what to tell you as for being able to use it. Just wanted you know you weren't alone.

Mine did this too but my son drank it with no issues. Sorry to hear that! Maybe you can try mixing it with fresh and see if she will take it that way. I used to use it to top off bottles here and there but at daycare he would some days get 3 full bottles of frozen and never balked.

Yep, lipase, as others said below. I have heard, though, that flash-heating it may help with the taste, so you may want to check into that to see if you can still use it.

My son never liked frozen breast milk. If it was fairly fresh frozen he would drink it but not if it was for a few months.

my milk did the same thing and my son wouldn't take it either. It was pretty much a waste of pumping and saving milk for me because I couldn't never get him to take it. Maybe you will have better luck then me though. I would try mixing a little bit at a time with the fresh breast milk until you can do a total frozen one...just an idea to try.

My daughter wouldn't ever take milk that wasn't fresh -- either from me or freshly pumped. I couldn't figure out why until I tasted it and it did taste off. There is a term for it, but I don't know what it is.
