Question about frozen Breast milk- please help!

Why is it that my milk, when I thaw it out, smells like it is sour?

The dates are recent, I am using it withing the allowed time frame... but it smells so yucky and I am afraid to give it to DS?

Am I doing something wrong?

Thanks!

I don't remember thawed BF smelling funny/sour. Maybe their is a hole in the bag or it wasn't sealed correctly? Sorry, IDK

WHAT ABOUT SOURED or "OFF" MILK?
Milk is not spoiled unless it has a sour odor or tastes bad. Some moms find that their milk seems to spoil rather quickly despite careful attention to proper storage and handling. This is thought to be a result of the milk having an excess of lipase, an enzyme which helps break down the fats in human milk. One way to keep milk from spoiling so quickly is to halt the breakdown of fats by scalding the milk just prior to storing it. This is done as soon after expression as possible and over a stove eye. Scalding the milk involves allowing small bubbles to appear on its surface but removing it from the heat before an actual boil occurs. The milk should then be stored immediately either in the refrigerator or freezer.

Other mothers have reported a soapy smell to their frozen milk after it is thawed. This change in smell has been attributed to changes in the milk fats related to storage in self-defrosting refrigerator-freezers. It has not been found to be harmful to the baby.

Sometimes odors from the refrigerator or freezer can enter stored breastmilk. To avoid this, be careful about your choice of storage containers (review the information above), consider adding a box of baking soda to the unit, throw out old leftovers and make sure any newer food is covered or wrapped tightly, and check that the temperature of your refrigerator or freezer is set low enough. .

I had the same problem that I thought my milk was spoiled. It didn't smell the same as when it was fresh. so I threw a bunch out. Bad idea. It was actually fine. I ended up using a bunch and DS had no problem at all. I wish I wouldn't have wasn't that precious milk. It also separates and looks funny. I did a lot of research on this and ask many people and it was ok. Good luck

I had a FREEZER full of pumped milk and it was all sour. You can have a lipase in your milk that does not agree with freezing, if you boil the milk first, it won't smell sour. Taste it, if it tastes sour. throw it away, if not, you can use it.
