As gross as it may sound, you can’t decifer the drinkability (Ya, I said drinkability) of brestmilk by how chunky it is, or what color it’s turned. I know, if you’re not currently breastfeeding, that’s not the most appetizing topic.
So how do you know whether breastmilk is still good or not then? If it smells or tastes sour, pitch it. Mostly, taste and smell. If it’s still good, it should pretty much be odorless, and taste like sugar water still. But there are also time lines that will help you through it.
Room temperature - Anywhere from 10 to 24 hours
In the fridge - Up to five days I would say is your safest bet. Remember, store milk in the back of the fridge, away from the door, and label every pumped bottle/bag.
In the freezer - Up to three months. Also store in back of freezer, away from door, and label every bottle/bag with the date.
Never microwave breast milk to thaw it out or reheat it. The microwave will heat it unevenly, and also kill lots of the nutritious value that breast milk is so famous for. After you've reheated breast milk, you should use it within the hour.
Following these guidelines when storing breast milk should keep your precious little baby's tummy feeling good!
